X-Cart forums

I recently upgraded to the latest version of XC5 and when I went to edit a category I got a the following error.

ERROR: "Includes\ErrorHandler::FATAL_ERROR" (code 2)

Maximum function nesting level of '100' reached, aborting!

I disabled all modules and then enabled each module one at a time until I discovered that Theme Tweaker was causing the issue.

It even happens with only theme tweaker enabled.
Anyone have any suggestions?

I will ask the normal question, is there anything more related to this error in var/log?

Hello!

Is Xdebug PHP extension enabled on your server? It sets a hard limit on the number of nested functions (i.e. a function that calls another functions that calls one more functions and so on) and may cause errors like this. You can try to disable the extension, or edit its configuration files and increase the limit.

Also, in recent versions of X-Cart we made a number of improvements to prevent this issue. So, if your X-Cart version is 5.0.13, it makes sense to upgrade it to 5.1.x or 5.2.x - this may help to solve the problem too.

I am running 5.2.3 and this is from the php_errors.log

As you can see it appears as if the AViewAbstract.php file is included recursively.
