Hello to the Administrative Panel Xenforo constantly there is an error how to fix it ???

What is the cause of the error ??

Which version of XenForo do you actually use? The allow_call_time_pass_reference directive has been removed from PHP a long time ago and even the oldest PHP version we support here does not support it.

I would like to remind everyone that running nulled software is not allowed on our hosting and risks getting your account terminated.

Xenforo version 1.5.6

Xenforo version 1.5.6
