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 ?
