First of all thank you for the useful extension WPMW. I 've been trying to install it in my wiki at http://domain.com/wiki/ . I follow the steps and add the lines to Localsetting.php:
require_once('extensions/AuthWP.php'); $wgAuth=new AuthWP();
But now I get Fatal error when accessing the wiki page (you can visit the link above to see the error) The Mediawiki install is fresh. The Wordpress Multisite is installed with Buddypress, bbPress. I think the problem is because of Wordpress Multisite since I tried to disable Buddypress and bbPress plugins but still got problems.
