Can't change/edit anything

[kathmandu]

hi.

I can create appointments but can't make changes after. Lets say i have created an appointment scheduled on at Location: room1. Now I can't change it to room2. It acts nothing and if i hit the close button, it says do u want to save? if i say yes it is not saving it.

What 's wrong with my zimbra server? Its not with calendring only same with tasks as well.

Thanks
Kathmandu
