CLOSED: Public/Private content in OMEROInsight and shares in

Hi there,
I'm new to OMERO and my administrator has installed the server.
When I load content via the OMERO importer this works fine.
However, when I view the files in OMERO insight -- the public/private radio buttons are greyed out.
Likewise in the Web client, when I make a share I get a server error (below).
Please can someone explain, how to make my images available to other users in my group?
Thanks
Mike
