Recently we’ve had several clients complain that their WP Admin is extremely slow. Today I created a staging site and turned off all the plugins, switched to a default twenty twenty one theme and started activating plugins one by one until the error occurred. I then turned off all the other plugins until only Gravity forms was active and the error still occurs.
The WP admin is terribly slow and there’s an error on the admin that says " There has been a critical error on this website. Please check your site admin email inbox for instructions." and the full plugin list doesn’t load. Our error logs show a timeout error
AH01071: Got error ‘PHP message: PHP Fatal error: Maximum execution time of 30 seconds exceeded in /var/www/vhosts/[domain removed]/wp-includes/l10n.php on line 1430’
I increased the max_execution_time to 60 seconds so the list loads and it doesn’t throw an error but it doesn’t resolve the terrible speed issue. I tried pulling an old copy of the Gravity forms plugin but it doesn’t resolve the issue so i’m not sure if it’s something in the database that’s causing the long load problem and that’s not being removed/updated with the plugin files. The live site is an ecommerce store so I can’t do a full database revert back to prior to the update.
