Alright. The console shows the following error:


 * Uncaught Error: Unknown dependency: jquery.collapsibleTabs load.php?debug=false&lang=en&modules=jquery%2Cmediawiki&only=scripts&skin=vector&version=20140825T0…:151

event.returnValue is deprecated. Please use the standard event.preventDefault instead.
