I have migrated a client's site from their old spammy domain to their new domain that better represents their business. However, since the move, there seems to be some kind of Javascript/Ajax issue.

For example, I can't seem to switch tabs (on ajax pages), and the useful "quick edit" tool doesn't work at all. When clicking the quick edit link on any page I get this error in the F12 console.

Uncaught TypeError: Cannot read property 'hasClass' of undefined

Press F12, go to "Network" and reload your page. See if all the content is from the new domain or something is calling the old one
