Problem: You are experiencing a PHP Fatal error on your website when using the WPML plugin's language switcher, specifically when switching back to the Dutch version from a category page. Despite increasing the zend.max_allowed_stack_size, the issue persists. Solution: We recommend the following steps to address the issue: 1. Save and remove the existing debug.log file from your server if it's too large, as it can affect performance. 2. Temporarily deactivate all plugins except for WPML and WPML String Translation to check if the issue still occurs. 3. Attempt to reproduce the error by switching between languages multiple times. If the error does not reoccur, it might have been caused by a conflict with another plugin. 4. If the issue persists, please provide specific steps or conditions under which the error occurs to help us further diagnose the problem.

Problem: The client is experiencing 404 errors on their website when switching between categories in the English translation using the WPML plugin. The issue does not occur on the source version of the website, and the server logs indicate that the page cannot be found. The client suspects a problem with the .htaccess file.
