My Theme isn't working 100% (libaries issue)

Hi, my website @ is having issues with displaying the slider images
and screenshot images on the homepage. i sent a support ticket to my theme developer and
he replied with the following:

"Hey Tommy,

It’s definitely a javascript conflict of some kind. Your Wordpress site is importing the Prototype/Scriptaculous libraries that seem to be conflicting with FreshServe’s jQuery libraries.
Any idea what plugin might be causing this? You can try disabling/enabling them one a time while refreshing the homepage to narrow down which might be the culprit."

What could it be? Thanks in advance for the support!
