 * Hi all,
 * Can you please help.
 * When I activated wp super cache I got some errors, I see it is related to AIO
   Wp Security. Please let me know if you are familiar with the conflict and the
   errors that appear? 
   Here is the error: [https://pasteboard.co/F5zxIrpKzaI0.png](https://pasteboard.co/F5zxIrpKzaI0.png)
 * Thank you.

 * Uninstall and install the plugin again. That should help.

 * Hi,
 * Thanks for reply, but it doesn’t help. I tried a lot of times.
 * This happens when I optimize the page using the one-click option offered by my
   theme. When I try to optimize, this warning first appears, and the WP Super Cache
   and Autoptimize plugins are not installed.
   And the message says that there is
   a problem with WP Super Cache.

 * Is it your theme, or is it AIO WP Security where this optimize button is?
 * The advanced-cache.php script loads wp-cache-phase1.php so it can serve cached
   files. The error you’re seeing says that “wp-super-cache/wp-cache-phase1.php”
   wasn’t found. Meaning that something deleted it.
 * If the error happens when you run this optimize process, then there’s probably
   an issue there. Contact the author and ask them why it is deleting WP Super Cache
   and Autoptimize.

 * Hi there!
 * Do you have updates about that? We usually close inactive threads after one week
   of no activity, but we want to make sure we’re all set before marking it as solved.
   Thanks!
