Javascript error on front page when loading new theme

I am currently using Blogolife 2.0 theme but want to change to mystique. When I activate Mystique I am getting this error message:
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 still get the message after deactivating all plugins.

Here is the site

Any ideas what the issue might be and how I rectify it?

Cheers
