Problem with install - cannot instantiate class - autoload_func.php

I've been trying to install zencart without success.

I've already uploaded all the files twice (different ftp clients), have created the configure.php files, modified access to files and folders (chmod), and always get a 500 server error page when hiting the install page.

Checking the error.log in the store (catalog) directory, the following error shows up:
PHP Fatal error: Cannot instantiate non-existent class: notifier in /home/mydomain/public_html/store/includes/autoload_func.php on line 79


Does anyone know how to sort this problem?

A neat thing this forum does is to put similar threads at the bottom of a new thread. After you post a new thread, it will see if anything similar has been discussed.

One of those at the bottom of this thread should be helpful as these things are almost always a bad upload or incorrect configure file.

Hey dbltoe, thanks for pointing that topic.
I searched for this problem here and couldn't find any useful topic before opening this thread.

Just for the sake of it, I uploaded everything again (third time), and double checked once again if files were corrupted, had the wrong access rights, etc.
Everything was fine, but still, it didn't work.

When creating the configure.php files, I also tried two different things:
1. Used the configure.php files exactly as in the dist-configure.php (no edits to those files)
2. Modified those files with the correct settings (domain, paths, url, database, etc...)

With option 1, I still get the same entry in the error_log file:
Cannot instantiate non-existent class: notifier

With option 2, I get no entries in the error_log, but still the same 500 error page is displayed.

With both options, I also tried the following code in the application_top.php file:

Code:

---

define('DEBUG_AUTOLOAD', true);

---

The same page was returned with no further error/debug messages.

Does anyone know what may be the problem? Or how I can get more insights about it?


I wonder if this problem is related to the settings in the server.
As I use a hosting company, I will not be able to change those setting myself (but can always request them if I know what is required).

Does anyone know if the server settings may be causing this problem?
Btw, where can I find the required setting (or settings known to cause problems to zencart)? (I believe there must be something already here in the forums, but I just searched for it and couldn't find).

Any help is very much appreciated.

Sorry,
read over the 500 error in your first post.
Have you looked at the log files on your host to see what error it is throwing?
Have you tried renaming the .htaccess file?
The 500 error tells us the problem in that the host server doesn't like something.
A link to the offending site is always a good way for us to "see" what's going on.

Can you please post a link to where this can be seen in action?

What are your server's PHP settings for include_path ?
(You can see this and other information by pointing your browser to www.your_site.com/zc_install/techsupp.php )

dbltoe and DrByte, thanks for your help and attention.

After not being able to understand the problem and install the latest version myself, I gave fantastico a try, and it installed okay. It simply works now.

I seriously have no idea what went wrong. I usually prefer to install all the scripts myself (not through fantastico), so I have more control over the install process, but was not able to crack down this problem.

So, now that things are finally working, I hope to become an active member here (i.e., addicted to zen-cart)... :wink:
Thanks again.

You should upload the zc_install folder to your site and see if it will run properly now.
Otherwise you'll have problems later when you attempt to do upgrades ... better to know now than to be surprised later.

I had a functioning store at my new host until a couple of hours ago - now it won't load and the browser is looking for the aforementioned zc_install folder. I don't see that folder on the "downloads" page here - where's the folder, Doc?

Sorry if I'm missing something obvious, I'm a little brain-fried - due to go live with the store at midnight and everything was working fine until this popped up. Help would be much appreciated & I will keep working on it as well. Thanks!

Yep - Totally brain-fried. The zc_install folder isn't supposed to be there, it's only for initial installation. So why is my browser suddenly looking for it? Very odd stuff and the shop was just working - and now it's not. Crazy.

BTW I ended up in this thread because I was getting an autoload error:

1-Dec-2007 16:00:44] PHP Fatal error: Cannot instantiate non-existent class: notifier in /home/tgadmin/public_html/shop/includes/autoload_func.php on line 156

Web site is www.transgentry.com if you want to have a look. www.transgentry.com/shop just won't come up anymore. I'm stunned.

Do I have to reinstall the store because I moved it? :shocking:

A URL?
Hard to believe that a functioning site completely dropped off the internet without a host problem.
No Admin or Cart?
The zc_install directory is part of the full cart download and not left behind when Fantastico loads a fresh cart. You can download the cart from here and upload the directory by FTP.

first its functioning and BOOM it quits. Then you say you moved it.:lookaroun

Have you made sure that BOTH configure.php files are correct with the move?
admin/includes/configure.php and includes/configure.php should both be correct. When they are not, the system looks for the zc_install directory to try to get the configure files ... well .... configured.

I lobbed an addendum in there on you, sorry. Going to generate a ticket with the new host, I seem to be having multiple issues so maybe it's not me. I have three accounts with them and none of the shops are loading. Index.html pages load but not the shops.

Thanks for your help, I will keep checking back in case you have some idea what might have snapped. Really appreciate the support I get here, guess I will be buying you donuts and coffee again soon!

*I'll go check those files - Thanks!

Change the .html files to .lmht and see if that doesn't work. Those should have gone by-by. I wouldn't delete them till you know they aren't containing something important.

You were right, the configure.php files had old info in them. Still not working though - now I get these errors:

Warning: is_dir() [function.is-dir]: Stat failed for /home/buzzardr/public_html/tgadmin/shop//includes/classes (errno=13 - Permission denied) in /home/tgadmin/public_html/shop/includes/application_top.php on line 132

Warning: Cannot modify header information - headers already sent by (output started at /home/tgadmin/public_html/shop/includes/application_top.php:132) in /home/tgadmin/public_html/shop/includes/application_top.php on line 132

Fatal error: Cannot instantiate non-existent class: notifier in /home/tgadmin/public_html/shop/includes/autoload_func.php on line 156


Should I still change .html files to .lmht?

Travel once again to both configs. There are several places where the information must be correct.

I am learning much, Sensei, but apparently not yet enough.

Decided to start at the top and fix the config files for the buzzardr home account, and did, and was able to get the BR shop to load there. Small victory. There's a red banner that says I need to change permissions on a config file but I did that. I'll worry about it later.

Went back to tgadmin and combed both config files, made the new changes I learned to make in the buzzardr config files. Saved everything and tried again - and got the same exact error messages again. But I will keep working. Since it worked for the buzzardr account, something has to work for tgadmin - I just have to find what's broke. Could be as simple as syntax, I guess. I will post again when I fix it - or if I decide to seek more help.

I get these errors for admin:

Warning: main(/home/buzzardr/public_html/tgadmin/shop/includes/autoload_func.php) [function.main]: failed to open stream: Permission denied in /home/tgadmin/public_html/shop/admin/includes/application_top.php on line 273

I will see if there's another place in the control panel to change file permissions - I was doing it in the file manager.

please post both your config files WITHOUT username and password. The two files mentioned in your error do not have 273 lines of code combined:shocking:

I returned both these files as close to how they were originally as I could; was basically undoing changes as soon as I saw what didn't work.

Actually the full path was originally written as: /home/buzzardr/public_html/tgadmin/shop/

The actual path appears to be more like:
/home/buzzardr/public_html/tgadmin/public_html/shop/

I did try this but still got the same errors. So then I truncated the path to simply /home/tgadmin/public_html/shop/ and got fewer errors - but that's probably because I diminished accessibility to my site.

buzzardr administers tgadmin. In the old account the path was just like this. In the new account I'm not certain how buzzardr ties to tgadmin. My new file structure doesn't show this - everything is separate.

I really appreciate the help I'm getting here - my brain is out of practice for this kind of thinking.

Okay.

I have compared the buzzardr config files that work, to the tgadmin config files that do not.

I have compared the config files from the old server that were working, to the new config files that, again, do not work.

I have made adjustments per these comparisons. The store still doesn't work.

As I see it now my options are to:

Try running a database repair, which is a little scary.

Try moving the Shop folder directly into the tgadmin home folder, where it was on the old server.

Reinstall the whole store and run a whole new gamut of issues.

Upgrade to v. 1.3.8a and, again, deal with a whole new group of problems.

They say whatever you are doing at midnight on New Year's is what you will be doing for the rest of the year. I don't mind that I'm working, that's a good thing. But I really would like to be successful before I give it up and go to bed.

I will therefore keep working.

I have now learned to use the code editor to quickly find lines cited in error messages. I'm very excited.

Apparently this line in shop/includes/application_top.php is exceedingly offensive:

if (!is_dir(DIR_FS_CATALOG.'/includes/classes')) header('location: zc_install/index.php');

I will keep digging.

brodybro1, you're having such a good conversation with yourself I almost hate to barge in. :smile:

In both your 'config' files, change the following:

- from
define('SQL_CACHE_METHOD', 'none');
define('DIR_FS_SQL_CACHE', '/home/tgadmin/public_html/shop/cache');

?>


- to
define('SQL_CACHE_METHOD', 'database');
define('DIR_FS_SQL_CACHE', '/home/tgadmin/public_html/shop/cache');

?>


See what happens.

LMAO! Thank the Gods, I thought I would never shut up.

This looks almost promising -

In shop I now get:

Warning: Cannot modify header information - headers already sent by (output started at /home/tgadmin/public_html/shop/includes/classes/class.smtp.php:2019) in /home/tgadmin/public_html/shop/includes/init_includes/init_database.php on line 57


In admin I now get this message:

0 DB_ERROR_NOT_CONNECTED
in:
[db_cache table]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.


I already went looking in the files for spaces in the php coding but maybe I missed something? :blink:

I keep seeing references to 'zc_install/index.php' in the lines of code referenced by the error messages. Is this significant to the problem at hand?

Going to try a database repair... someone else had the "Cannot modify header information" error and I also have the DB_ERROR_NOT_CONNECTED so...

*Nope, no difference.

NEXT -

Every place where zc_install/index.php is referenced is inside a safety condition clause that will only send you to zc_install if the safety check fails.

Common causes of the failures are:
- incomplete uploads of all the files on your site (did your FTP upload fail on anything? are you SURE?)
- incomplete configure.php files
- incorrect contents in your configure.php files
- incorrect settings for accessing your database ... in the configure.php files.

Here's an FAQ on the move process: https://www.zen-cart.com/tutorials/i...hp?article=100

You might need to do a comparison of what you uploaded vs what you attempted to upload (by re-downloading it to another folder, and comparing the folders): http://www.zen-cart.com/wiki/index.p...Obscure_Issues

And you will need to be sure your configure.php files are correct.
One way to get correct configure.php files for the new server is to do a FRESH install on the new server, preserve the generated configure.php files, and then import your database again ... as explained in the FAQ.

:frusty:

As much as I'm enjoying navigating the labyrinth it's probably best if I just start over. I really wanted to win this one but you're right.

Tomorrow I will back up my databases and shop, and do a fresh install. Compare the configure.php files so I can learn what a Proper configure.php file looks like. It'll just Work if I do that.

Thanks for all the help, I'm learning it. And I'll make another donation when I get paid again, for sure.

Happy New Year - Brody

Follow-up: I got my store up the next day & so far everything works now. What's truly sick is, I can't wait to build another one with v1.3.8a,and to start modding on both of them.

I think I've been Zenned. Thanks again for the great help - and tremendous patience - all of you offer up here on an hourly basis.
