Zend OPcache not working properly


I've 2 account on the server, both use PHP7.1 and have Opcode Caching Up and Running. On one account it working properly but for another, the cache hits date reset after a few seconds which mean no benefit from opcode.

Do you know any setting would effect that please?

Thank you, I missed a step, now Opcache is working for all accounts.
Anyway, how can I enable suEXEC ProcessGroup Mode via Litespeed web interface please? I only see suEXEC Daemon mode.

Thank you.
