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.
