Forumlar / Cotonti / Support / links/buttons don't work

hey

i have a small problem.. we are running the latest version of cotonti and the links in admin panel don't seem to work.. for e.g. clicking on the main links like "home/configuration/pages etc" works fine but when in "configuration" page you can't click on any of the links(comments,forums,language etc) they simply do nothing when clicking.. but if you right click and go to open it, it will work fine.. same with buttons except that you cant "open" them by right clicking.. any help on finding the problem? i think it happened after updating from 6.7 one by one to 6.13.. and then 6.14.. i might have missed something but what?!
