Hovercards and other hover over image functions don’t work anymore!

If you look in the source code of your homepage, in the header you will see that you have a lot (infact i have never seen as many jquery files in a header before) calls to jquery files, this is definatly a cause for conflict if two of the files are the same, i can see at least 2 references to a similar file.

What you will need to do, is deactivate all plugins, and start reactivating them one by one, each time testing the site, eventually you will activate the plugin that is breaking your jquery what you can do then is open up that plugins files and comment out the line that calls the jquery file and see if it will run off the other one..

these could be the issue
