Urgent fix for jquery/php issue on the site

Well, something happened with my site. Suddenly Jquery stopped working. There are now 2 functions that stopped working. The code, CSS, everything seems to be correct but something is causing the conflict. I have 4-5 Tabs, clicking on this Tabs should appear a relative information. If not clicked they should remain hidden, like all Tab do. In my case, all information under those 4 Tabs are visible and messed up. Need quick fix for them. Other task, a notification message which is JS stopped appearing. When you add new item or when you rate the item new small notification should appear but for unknown reason it also stopped working. Coding and other stuff is done! Just need fix! Pm me for URL and details.
