Fatal error Cannot redeclare class

[sasha21]

Hi everyone, good day.

We have had a new template and all the site was working just fine, but we wanted to install some add's, one of them is shopmania...

I'm able to enter the admin area, but unable to see the store front (which gives error code 500), I was attempting to put shopmania's code on my site and I wanted to set it on the index.php, so I opened the file and pasted the code they gave me, but at the end I deleted it (leaving all the file like was before editing) because the store owner just wanted the banners made for the site.
Contacted hosting provider about the error code 500, they said maybe in the .htcaccess was modified the .php or .html, we didn't editted the htcaccess, so this was no that helpful.
I also updated the file datafeed_shopmania_zencart.php in the directory which is suposed to be uploaded (meaning www. importamx .com/Tienda this is were our store is installed), and it work fine.
The store can be seen if the site is put on maintenance.

I have checked the debug log and it shows:

PHP Fatal error: include() [<a href='function.include'>function.include</a>]: Cannot redeclare class base in /home/content/54/10372554/html/Tienda/includes/autoload_func.php on line 60

I have searched into the Developers Tool Kit and I got:

Zencart v 1.5.1
MySQL 5.0
PHP 5.3.24
The web is importamx .com

Summarizing:

The file datafeed_shopmania_zencart.php has been loaded in to the store file root
The index.php has left like was before editing
Restoration of DB has been set to a point 23 hours ago (didn't help).
Compared autoload_fun.php with zencart's original and the one in the site.
Compared configure.php files
Compared index.php files

Thank you in advance.

What are the differences when you compare *everything* ... ie: ALL files, not just 3.
What files are missing?
What files are extra?

Hi, DrByte.

I executed WinMerge and it shows several extra and different files, although I still can't find what is causing the error.

Equal files:
download, editors, extras, logs, media, pub.

Report attached.

You need to look at all the files in your /includes/ folder and subfolders. Delete any extra files that don't belong. Remove changes to changed files that don't belong.

Hi again.

The extra and different files in the includes folder are the ones modified for the custom template, I have been checking file by file (though maybe I have missed something). The problem still persist, so I have set the store under maintenance (the way still shows the front store), while I'll upload a new zencart (tested in localhost) to replace the broken one.

I have checked the debug log and it shows:

PHP Fatal error: include() [function.include]: Cannot redeclare class base in /home/content/54/10372554/html/Tienda/includes/autoload_func.php on line 60

That was the wrong search.
The filename in which the error occurred is only the "messenger", not necessarily the actual error.

In your case, your site is somehow loading the /includes/classes/class.base.php file multiple times. That could be caused by having files actually trying to load that specific file (which should never be necessary), or by you making duplicates of other files when renaming them to "make backups", or by you adding code that re-runs the autoload_func script multiple times.

About the "renaming to make backups" comment: NEVER rename "something.php" to "somethingelse.php" in order to make a backup! Change the ".php" part, not the filename part. So "something.php" should be renamed to "something.bak" or "something.php1" or "something.old" or "something.php-old", etc.
Zen Cart automatically loads all "*.php" files in many folders just by virtue of their existence. So if you rename and "old one" but keep the ".php" on the end, you're not actually stopping the "old one" from being used, but instead you're making it be run TWICE ... which will often result in errors similar to the symptoms you're reporting.
