OWA calendar month view problems   

We have applied SP1 to obtain the Exchange 2007 OWA calendar monthly view. 
The view is corrupted for users. The calendar grid is present but no events 
or dates display. We have customized our theme so maybe that has caused a 
problems? How can we reset? maybe?
