Problem with Every Type of Photo Slideshow

Hello. Hopefully you get this message and reply ASAP, since the last reply I got from a previous post that was posted months ago only recently got a response.

Starting about a week ago, a photo sildeshow plugin stopped functioning on my company’s website. I tried reverting back to older versions of the slideshow and also other plugins, as well as reverting back to older versions of wordpress. I have also tried to install and test other slideshows, which do not seem to function either.

Here’s a web link with an example:

Can you provide any help with this? Our hosting company has hinted it may be an issue with the theme. Thank you very much in advance.
