I’m having a similar problem, and I tried installing the Google Libraries Plugin, but to no avail.
I’m getting the error:
“Uncaught TypeError: Cannot read property ‘apply’ of undefined”
In Chome’s Developer Tools, originating on line 9 of jquery-ui.min.js.
Interestingly, it doesn’t seem like installing Google Libraries actually had any affect, as everything is still being loaded from the site itself, not from Google’s CDN.
Any thoughts?
