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
