Hi,
I am getting this on a new installation of Mediawiki on Centos 5 with PHP 5.4.20. After a successful install, and upload of LocalSettings, I get the following error when I try to access the site:
PHP Catchable fatal error: Argument 1 passed to ScopedCallback::__construct() must be an instance of Closure, unknown given, called in /var/www/html/mediawiki.prepis.org/includes/cache/MessageCache.php on line 344 and defined in /var/www/html/mediawiki.prepis.org/includes/ScopedCallback.php on line 33
Any tips would be greatly appreciated.
