AJAX Gremlins?

I may be imagining it, but I’m sure ?i have Ajax Gremlins in my site (hypnosisnorthampton.com).

About a week ago, I tried out a couple of ajaxified contact forms (contactMe and slick forms). But I noticed that they caused the slideshow on my site to stop. So, I deactivated them, but it still didn’t work. I even deleted the plug-ins with no difference.

I also noticed that the built-in testimonial rotator, that works via a shortcode, had stopped working. I’ve since had to use a plug-in to get the same effect.

Is it possible that the plug-in left some residue call to Jquery or something that I need to delete?

Any help would be greatly appreciated.
