Hello,

I'm upgrading MW from 1.21.3 to 1.27.0. I have an error concerning the latest stable release of AccessControl :

Strict standards: call_user_func_array() expects parameter 1 to be a valid callback, non-static method AccessControlHooks::accessControlExtension() should not be called statically in /var/www/wiki/includes/Hooks.php on line 195

I'm running PHP 5.6 on UBUNTU 16.04.

Does someone have any idea how to solve this problem ?

Strict standards warnings shouldn't be displayed on production environments, try disabling those errors. disable strict standards error.

Assuming it's just a warning, it may work.
