Please send VPS access details so I can have a look, on another thread I also noticed that you have manually installed openlitespeed, which can create some issues.

No , this happens before I tried to reinstall OLS manually

VPS info send in PM , please have look

Language was something other than English which CyberPanel was not able to read.

localectl set-locale LANG=en_US.UTF-8

This fixed the PHP issue, also added this fix to installation.

Thank you for pointing out.
