While the current Time Limit is set to 1200 seconds (20 minutes), this may still not be sufficient for processing 17,000 products, especially if the operation requires significant server resources. I recommend temporarily increasing the time limit further to see if it helps.
Example to Increase Time Limit:
You can increase the time limit by adding the following line to your php.ini file:
max_execution_time = 3600
This will extend the time limit to 3600 seconds (1 hour). Alternatively, if you can't access the php.ini file, you can try adding this line to your .htaccess file:
php_value max_execution_time 3600
Max Input Vars: The current MaxInputVars is set at 2500, which could cause issues if a large amount of data is being sent in a single AJAX request. I recommend increasing this value to 5000 or higher.
Example to Increase Max Input Vars:
To increase Max Input Vars, you can add this to your php.ini file:
max_input_vars = 100000
Or, if you're using .htaccess, you can add:
php_value max_input_vars 100000
If adjusting these values does not resolve the issue, I recommend testing the setup in a minimal environment (with all plugins disabled except the necessary ones) to rule out any conflicts.
First, you must check if the problem persists when just the theme is switched to TwentyTwenty-Four (for example). If it persists, deactivate all plugins except WPML and its add-ons and WooCommerce without any extensions. Then, please check if the problem persists. If it does not continue, start by activating the plugins individually and checking when the issue comes back, then report to me which plugin was the culprit.
**** Important! Please make a full site backup (files and DB) before you proceed with those steps****
*** If your site is live, you might want to try those procedures in a staging environment or a snapshot of your site on your local server or another server. ***
