Hello:

I have deleted all users I had add in the site. I can't see them in Dotnetnuke admin users tool. I have deleted them and after that, I made a hard delete. No users.... but whe I try to create a new one with an old name, system says that then name is in use....

So I went to the SQL Server anda I've seen that users still in dbo.aspnet_Users and in dbo.Users (in this table, the field IsDeleted is "False").

I have a brand new installation (needed to try to solve this problem:
(Error trying to follow an user)

Same deletion process delete users from SQL tables.

Any Idea?  Could it be the same problem that causes the Error trying to follow an user?

Can I delete users manually from both tables? Need I to delete something else in another table? Can I delete all messages and notifications?...
