JS Not Working Throughout The Plugin?

For some reason the Javascript aspects of the plugin in the admin are not loading.

e.g Event Details within an event the accordion only open on the first one, ‘event location details’ below wont open when you click on it.

Also Settings ‘Show form’ doesn’t do anything, just a hash tag in the address bar.
Below that
Viewing Events
Adding/Editing Events
Advanced
Clicking on these nothing happens apart from the hash tag again.

Theme options again, cannot click through the tabbed pages.

Any help will be much appreciated as the plugin is currently useless 🙁
