Well the issue is caused by the dnn menu you are using and not the forum! What menu are you using in your dnn skin?
You were right,
everything works in standard DNN skin.
Now the only problem is , I am the only one that can access the forums.
everyone else gets this error...
Cannot insert the value NULL into column 'Flags', table 'sejlklubbenKBH_DATA.dbo.yaf_User'; column does not allow nulls. INSERT fails.
Cannot insert the value NULL into column 'UserID', table 'sejlklubbenKBH_DATA.dbo.yaf_UserGroup'; column does not allow nulls. INSERT fails.
The statement has been terminated.
I have imported users.... there is a filled table for users DATA.dbo.yaf_User
