I get the same error when I swapped out the version of jQuery that WordPress ships with and swapped in jQuery version 1.7.2 (the same version that your theme is using). You can fix this by ensuring that the current version of jQuery is used.
You can contact the theme author and they may have an update to the theme. If they do not, then the next step is to find where the older version of jQuery is being added to replace the version that WordPress ships with, and remove that code. You might also need to update the other jQuery plugins that the theme has if they aren’t compatible with current jQuery libraries.
