Hi and thanks for the prompt reply!
Yes the issue is that the calendar shows up but none of the posts are loaded in and I can save no new posts in it. I can enter Unscheduled Posts in the right column but I cannot drag and drop them into the calendar.
There are no apparent errors, but I am not a very technical person and my tech guys are on holiday:( I am using WordPress version 3.3.2 for my blog.
Thanks for your support!
Mihaela
