 * That means you didn’t fully uninstall the old caching plugin, so you have a persistent
   cache and nothing to clear it with.
 * Consult your caching plugin’s instructions for the full uninstall procedure.

 * What is the name of the caching plugin you were using?

 * just to be clear; Autoptimize does not do page caching, just JS/ CSS/ HTML/ Image/
   Google Font optimization.

 * Ok, you’ll need to go step-by-step through each one’s full uninstall instructions.
 * Deleting just the plugin’s files is never enough for deleting a caching plugin.
 * Instructions on fully deleting WP Super Cache are under [https://wordpress.org/plugins/wp-super-cache/](https://wordpress.org/plugins/wp-super-cache/)
   but I find [https://www.nethostingtalk.com/viewtopic.php?t=279](https://www.nethostingtalk.com/viewtopic.php?t=279)
   to be a bit clearer.
 * For WP Fastest Cache [https://www.nethostingtalk.com/viewtopic.php?t=288](https://www.nethostingtalk.com/viewtopic.php?t=288)
 * For W3 Total Cache, see “How To Uninstall W3 Total Cache WordPress Plugin” under
   [https://wp-rocket.me/faq/w3-total-cache-fixes/](https://wp-rocket.me/faq/w3-total-cache-fixes/)
 * For AutoOptimize [https://wordpress.org/support/topic/deleting-autoptimize-cache/](https://wordpress.org/support/topic/deleting-autoptimize-cache/)
