This thread is resolved. Here is a description of the problem and solution.
Problem:
If you're experiencing a 500 error every time you update WPML plugins, despite increasing the memory limit and deactivating and reactivating plugins, follow these steps to diagnose the issue.
Solution:
We recommend enabling the WordPress debug log to capture more specific error messages. Here’s how you can do it:
1. Edit the
wp-config.php
file in your WordPress directory.
2. Insert the following lines:
define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true ); define( 'WP_DEBUG_DISPLAY', false );
3. Try to reproduce the issue. After this, you should be able to find the debug log at: /wp-content/debug.log
4. Upload the content of this log to a site like pastebin.com and share the link with us for further analysis.
