Something, likely the theme, is including an older version of jQuery instead of the newer version bundled with WP. In addition to an older version being loaded, it is being loaded from Google instead of the version included with WordPress. That later isn’t necessarily bad if done correctly, but it is not. This will lead to breaking to many plugins.
My suggestion is to enable the jQuery Fixer option of the Connections : Settings admin page under the Advanced tab. This option attempts to correctly load the correct version of jQuery that is bundled with WP.
That should fix it. Let me know.
