Hi John,
One thing that immediately jumps out is that you are using jQuery 1.7.1. The current version of The Events Calendar requires at least WordPress 3.5 which ships with a much higher and more recent version of jQuery, and naturally expects that to be present.
It may be that some custom code you added, or else your theme or another plugin is for whatever reason substituting the default build of jQuery that ships with WordPress for this much earlier version.
Could you either try our normal troubleshooting steps (themes are a common culprit so it would be as well to start there) of switching to a default, unmodified theme such as Twenty Twelve and then deactivating all non-Modern Tribe plugins to see if this is then resolved.
If it does resolve this, then reactivate each one-at-a-time until you isolate whatever is causing this – assuming for the moment this is due to your theme you may wish to touch base with the theme author and ask how this can be remedied/check if fixing this will impact on anything else.
Does that help here?
