Class 'tableBlock' not found

[Sean Maher]

Hello,

I just have a query in regards to the following error messages that I receive in the myDEBUG-xxxxxxxxx-xxxxxx.log for my Zen Cart site, I can't seem to pinpoint the issue and it is frustrating me to no end :)

[13-Jul-2013 00:20:59 Australia/Melbourne] PHP Fatal error:  Class 'tableBlock' not found in /home/bundysup/public_html/shop/includes/classes/message_stack.php on line 22

So when loading the site I get a 500 Internal Server error (blank white page) and that message is logged. I have recently just upgraded form 1.3.9h to 1.5.1 using the Installatron provided with the websites CPANEL interface. There was no issues (apart from the above) that occurred during the upgrade.

I have confirmed that the file which contains the 'tableBlock' class exists in the directory being referenced in the error,I have also confirmed that this file (table_block.php) exists in the folder which the error message references AND is being included by /home/bundysup/public_html/shop/includes/auto_loaders/config.core.php

I can login to the zcadmin section of the cart without any issues, it just seems to be the site that is affected.

Server Versions:
Database: MySQL 5.5.32-cll
PHP Version: 5.3.19 (Zend: 2.3.0)
PHP Memory Limit: 128M

I look forward to your response which would help me progress with resolving this current issue and hope I have provided sufficient information to assist you in this matter.

Thanks and kind regards
Sean

Check that the files are current, on the server, for:
/your_admin_dir/includes/classes/box.php
/your_admin_dir/includes/classes/message_stack.php
/your_admin_dir/includes/classes/table_block.php

with those in v1.5.1 ...

Using automated tools to upgrade is never recommended, as they cannot know or handle all the customizations you have made to your files. If you had a customized file in your template folder, and the corresponding base file was changed in the new ZC version, you will still be using the old customized version of the file until you manually compare and merge the file versions.
If you customized a file in its default location, or a file for which no override is available, your customization will be wiped out without a trace by the auto-upgrade.

Ok... So what you're implying I must do is to run a diff tool to compare the differences between files that may have been changed from the vanilla install of Zen cart... Or files that may be missing.. But you are unable to tell me why it is failing to detect the class? Where else is this class used? I realise the error is obvious, but doing a search for this class does not seem to find it im any other locations. That's fine I guess I will continue to troubleshoot this issue myself. Thanks.

Any chance you're using the old PayPal IPN/Standard payment module on your site?
Any chance those errors are occurring when that payment module encounters an error situation?
Any reason why switching to Express Checkout instead of Standard can't be done?
