After we uninstalled our DNNMasters.MPUS-Xtreme 1.0.41 module from our website (*note - We had also unassociated all associated portals from the module interface on the website and made sure that the "Delete files" box was checked beside the uninstall link.  Additionally we confirmed that all modified entries within the web.config file were set back to the DNN core providers) we started experiencing an issue when trying to register a new user to our DNN website version 4.9.00.

The issue occurs when we now attempt to add (register) a new user to the site.  After entering in the user's information on the registration screen, when you click the "Add New User" link - we receive an error on the screen which reads: "An Unexpected Error Occurred During Registration. Please Contact The Portal Administrator For Futher Information."  (*Extra side note for DNN corrections in next version - The word "Futher" is misspelled.  Should be "Further")

When we look in the database, we can see that the user has been created in the following tables: dbo.aspnet_Membership, dbo.aspnet_Users and dbo.Users.  However, we do not see the user (userid) in the dbo.UserPortals table.  This of course does not allow the user to be display in the list of users in the DNN portal.  If we manually create a record in the dbo.UserPortals table, the user will show up in the displayed list, but of course the normal registration process that would have assigned him his default roles have also not been created.

Is there any advice you can offer us regarding this issue that might help us look in a certain area of stored procedures or functions, etc. to try and correct the problem back to the proper way the DNN core processes should work?  Our site is a kind of virtual paper weight if we can't add any users. :-(
 

Thanks for your time and assistance.
