I installed W3 Total Cache. Shortly after configuring it, I began getting this error message:
Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate 9844552 bytes) in /home/…/wp-includes/wp-db.php on line 2022
This happened on almost every page I attempted to navigate to–even when trying to get to the dashboard. I have deactivated the plugin but I still have the error making my website unusable.
Is there a simple fix that a non-technical person could implement?
