I get this when I try to save the admin user account in BackOffice - even if I didn't make any actual changes. I get the same error when trying to save an additional adminstrator account I've set up, but save succeeds when saving a mortal user account. I'm using a rather obvious default password for my admin account, and would very much like to change this and other account properties before I deploy.

This is the error I get:

An error occurred while processing your request.

Exception
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
