I was wondering whether someone might suggest where I might start looking for a few minor but troubling errors I have in the Admin Screen?
 Running Firebug, the console gives me an error trying to run this script - http://notifications.vertical3.com/?feed=json&jsonp=jQuery18303490644491014805_1366185672748&_=1366185679608
Thing is, I have no idea where this is being called - it's listed in Firebug as read and failed
 Sometimes when I click on the Comments nav bar item, I get a pop-up which simply lists my domain URL. And this sometimes happens with other menu items but not always.
Weird, I know.
Any ideas how best to track these things down. I've run out of ideas myself.
Thanks for any help.
