Mystique theme, blank website

I’ve been using the mystique theme for most of this year with no real issues. However, I was trying to update my header picture (site logo) in the mystique settings earlier today. The picture kept uploading, however, whenever I saved it reverted back to my old picture. I have never had issues with this before, so I decided to try changing things and then come back and change theme back to mystique.

Changing to another theme went fine, however, when I changed BACK to mystique, my entire website went blank (white screen). When I go back into the mystique settings page I get the following error:

It appears that your home page has javascript errors on it. Deactivate all plugins, then activate them back one by one to find out which one is causing errors.

I did what it said and disabled all plugins, but that did nothing. Then while they were all still disabled, I tried changing themes again (other themes fine, but when come back to mystique same problem). I then deleted the mystique theme and redownloaded it, but that also did nothing to help with my problem.

My website is http://www.crystalfun2race.com Any feedback/suggestons would be greatly appreciated as I don’t know what to do, and I really don’t have the time to setup a whole new theme. Thanks!
