Oh, i see the same class wp_auto_update is defined in the plugin js_composer.
Ok, you should change the Option hoverPause: true to hoverPause: false in the File adrotate-output.php line 512.
That solved my problem.
Looks like the Framework jShowOff you are using causes this problem, they have the same on their website … (http://ekallevig.com/jshowoff/)
