This problem seems to be being caused by a bug in the DNN core, which at this rate I'll have to write a work-around for.... Please run this query:-

Select PortalId,RegisteredRoleId from {databaseOwner}{objectQualifier}portals  where portalid = P

Where P = the PortalId for the site with the problem. In your case this is 9 as shown in your error log output. Then run:-

select RoleID, PortalID, RoleName from {databaseOwner}{objectQualifier}roles where rolename = 'Registered Users'

I suspect you will find the RegisteredRoleId returned in the query does not match the RoleId for PortalId P in the second query. If so run:-

Update {databaseOwner}{objectQualifier}portals  set RegisteredRoleId  = R where portalid = P

Where R = the RoleId for PortalId P in the second query.

[EDIT] - To make this change effective you will then need to clear the cache, by going to Host Settings --> Performance Settings.

I have written this response in a more generic form, to help other who may have the same problem, and guide them how to construct the queries.

Cheers
Roger
