Image Handler 4 (for v1.5.x) Support Thread

[marieAA]

Hi,

I'm in my fourth try to install IH 4 and it's not happening for me. I use Firefox, Dreamweaver and Filezilla for transfer. I did the drag and drop thing for the files... everything shows as the instructions say however, when I get back to clicking a link on my admin, I get the blank page.

I can't get the auto-installer to kick in. I've checked the logs for errors and nothing shows there. I've found on the net that if my default language was other then English, removing the other language, installing IH and reinstalling the language could work, but it did not for me.

I've also found on this thread that for some, the admin>includes>configuration.php file was getting modified automatically in regards to the admin folder but mine isn`t. It is as it should be

define('DIR_FS_ADMIN', realpath(dirname(__FILE__) . '/../') . '/');

I have the latest Zencart installed

I did a file compare on the zen cart original file YOUR_ADMIN/includes/modules/category_product_listing.php and mine with Beyond Compare and the file was unchanged so went ahead and installed as instructed...

still no go... am I missing something?

Blank page = an error log.. so without know what error is being kicked out, I couldn't begin to guess what's going on.. Post the error logs generated when you install..

[marieAA]

sorry, I still have nothing in the logs folder of the store. and no error log on my host either. I see that some posted images of a list of errors that shows up at the top of the page.. is there a way to turn that on?

I've been running one of my client's test stores with error-reporting level E_ALL and wound up with a bunch of E_NOTICE logs of the form:

Thanks for this.. will make the change and submit update..

sorry, I still have nothing in the logs folder of the store. and no error log on my host either. I see that some posted images of a list of errors that shows up at the top of the page.. is there a way to turn that on?

The list of errors at the top of the page appears when the auto installer tries to process the files and comes across an error in that process.
Btw, the configure.php file is not touched by the installer, the fact that your file contains what you showed, indicates that ZC knows where the admin directory is and no changes to your configure.php should be expected by IH.
You stated that you did a file compare of one file, but did you do a file compare with all core files modified by IH as part of the instructions? Ie was this a first time install, or an upgrade? (Verifying the meaning of the statement of fourth time trying to install IH4.) Cache and sessions were cleared? Anything presented when viewing the source from within the browser? Do you happen to have a cache folder in addition to a logs folder and did an error get logged into the cache folder? (Yes I'm guessing at areas, because there really should be an error somewhere about this lack of system response.) Is there possibly so many error logs that the system is slow to respond to provide the list of error logs which contains the error associated with this event?

fourth try installing it for the first time... not upgrading.

Nothing at all when looking at the source.. I get this:

<html>
<head></head>
<body></body>
</html>

I did check on the other core files but didn't do Beyond Compare on them because all of those were original files for me, I didn't modify any of them prior to IH. I did check the cache folder, sorry should have mentioned it, and this one too is empty. I can't figure it out. Every single time I revert to my older backup, everything is running smoothly, no errors and everytime I try to put in the files again, blank page again. As for the quantity of errors, I would have had to have other errors prior to IH to make a list so long right? Things is that I fix all errors as I find them and there are none prior to IH and I don't get either why nothing happens when I add the IH files. I'll try again from the beginning again.

[marieAA]

My apologies for taking of your time. I had done a major stupid. I always take a fresh copy of my site and place it in a separate folder to test new mods to make sure I don't break the live one. While looking again at the configure.php files, I realised that I had forgotten to rename the store folder. So the errors were getting logged in the live store folder.

and if it can help anyone else with a different default language, I installed it again while having the default different language installed and it wasn't an issue at all. So no need to remove the language etc...

My sincere apologies, all is well now.

Hi,

Can someone put me in the right direction here, as my main images are not showing in zen-cart-v1.5.1-full-fileset-09182012

I was using Image Handler 4 for v1.5.x - Version: v4.3.1, but it did not show the images in the IH manager in admin (see post above - and included screen shots), so I did a complete uninstall of IH4.3.1 (used the IH built in uninstaller from ZC_admin), and deleted all the files that IH left behind (checked against the original IH file structure), also deleted the bmz_cache folder.

As it is suggested in your image_handler_readme.html, zen_lightbox needs to be installed (or some files to be re-written) after IH installation.

Therefore I uninstalled zen_lightbox-v1.6.4_1, by manually deleting all the files and running the uninstall.sql to make sure that nothing remainde of both IH and zen_lightbox installations.

Following your install instructions, I did reinstall Image Handler 4 for v1.5.x - Version: v4.3.2. In ZC_admin the installation went ok (all green messages).

Then I proceeded with the installation of zen_lightbox-v1.6.4_1

Here is the URL of a test product:

Looking at the DOM source of the page, I am puzzled by looking at the directories that the images are located in:

So please can you tell me what went wrong, and why I have 2 different URL's showing?

Many thanks for your help,

If understand correctly, in places that are normally a medium image, are wondering why IH4 doesn't override that. For that, read the instructions. Medium images are not handled by IH. I forget the explanation why, but if you want a different image to be displayed so that it is handled by IH then would need to change the ZC code to display a different sized image in place of the medium image.
