[Plugin: All-in-One Event Calendar] Was working, now can't change views, months

Hello, this was working perfectly and I launched my website last week but today it was brought to my attention that the calendar won’t move from one month to the next, OR change views from Month, Week, Agenda.

Someone else had this problem and it was a thickbox issue, but can someone help to determine what might be causing this on my site? I’ve deactivated other plugins to see if that fixes it, but so far, no luck.

Any help would be appreciated. Thank you!
