Thread:Extension talk:ShortLinks/error $link.attr("href").match(/ \?& title=(.*?)&/i) is null

Hi nice extension works good. Im using mediawiki ver 1.17 I dont have any problem with the functioning of this extension but firebug keeps on throwing an error "$link.attr("href").match(/[\?&]title=(.*?)&/i) is null" please tell me what is causing it?
