Hi Geraint,
I just set up a new test page with Joomla 3.0.
Of course I also installed JEvents 3.0 on this page. Installation was ok without any errors or problems! Great!
I went trough the configuration of JEvents, added a test event and added a menu item for Jevents (monthly view). No problem in the backend.
Frontend shows up ok too.
Will do some more testing tomorrow or early next week. 
If you would like to have details of my test page or backend access just let me know.
Have a great weekend,
TopCop
