I see now. It says that the issue comes from our plugins, but it’s not the case.
The problem is the jQuery in your theme comes from an ouside source and the version it enqueues is heavy outdated: http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js
It should never be like that in the theme. The theme should be using the jquery version shipping with WP itself. That’s the critical issue to be fixed by your theme developer.
