Thread:Project:Support desk/Update.php error

Hi.

I try to update mediawiki with update.php script but there is some error:

Going to run database updates for trouse_ws-wiki_ Depending on the size of your database this may take a while! Abort with control-c in the next five seconds (skip this countdown with --quick) ... 0 PHP Fatal error: Call to undefined method MysqlUpdater::tableExists in /home/trouse/domains/westeros.pl/public_html/wiki/extensions/AJAXPoll/AJAXPoll_body.php on line 404 Fatal error: Call to undefined method MysqlUpdater::tableExists in /home/trouse/domains/westeros.pl/public_html/wiki/extensions/AJAXPoll/AJAXPoll_body.php on line 404

What's going on?
