Hello,

Try restarting NGINX / PHP first.

Kind regards,

Tried alot time

Hello,

This requires server-side investigation (I assume you havent done core modifications). I think this might be related to a custom modification of some sorts but I can not investigate because I solely have an error log.

I do have one more question, do you happen to have a Windows server?

Kind regards,

Its centos 7 its work with fastcgi handler without any changes but FPM getting that errors.
Also error logs turn same following errors
