XF 1.4 Deleting thread

I'm a recent convert to Xenforo, and have been working my around it. I am having an issue and couldn't find the issue.

I am trying to delete threads from the forum and I click on delete thread, and the little working box just keeps going. Here is a quick screencast http://screencast.com/t/wdJBC2IE.

Thanks in advance.

This is likely caused by an add-on.

It would be wise to test it with all add-ons disabled first. Then re-enable each one to see which one being enabled causes the problem.

Also, the browser Developer Tools and specifically the Console may give you some indication as to what the error is.
