Question

How to enable / disable OPcache for a domain in Plesk?

Answer

1. Log in to Plesk.

2. Find PHP version used by the website at Domains > example.com > Dashboard tab > PHP.

   

3. On the same page, verify that:

   • opcache.enable is "on"

   • disable_functions setting does not contain OPcache functions (by default, opcache_get_status is disabled)

     Note: To disable OPcache for the domain, switch opcache.enable to "off".

     
     

4. Verify that OPcache is enabled in global PHP settings at Tools & Settings > PHP Settings > PHP X.X handler.

   
   

   Note: OPcache statistics are available at Domains > example.com > PHP Settings > View the php_info() page - cache hits, cache misses.
