This is my first DNN install (though I have been through the process several times so far).  My current problem is that several modules that i try to add give an error when trying to add a record.  This doesn't seem to be related to a single specific module - and it doesn't apply to all modules.

Example: the Events module - Select Add Event and i get "Error: Edit Event is currently unavailable."

Example: Help Modlue - basically the same thing.

However, the Announcements module works fine. 

I have made the DB user a db_owner.  I have given the Network Service full rights to the folders.

Any suggestions?  Thanks.

Make sure, both database connection strings in your web.config file are identical.
