I realize this is not the correct place for this, but I really dont know where to look and hopefully you can point me to the correct location.

DNN has started setting the users.firstname, users.lastname to '' (Blank).  I ran a trace on the DB and here is the code see where @2=N'',@3=N'' is set to blank.

exec sp_executesql N';Exec dbo.UpdateUser @0, @1, @2, @3, @4, @5, @6, @7, @8, @9, @10, @11, @12, @13, @14, @15',N'@0 int,@1 int,@2 nvarchar(4000),@3 nvarchar(4000),@4 int,@5 nvarchar(4000),@6 nvarchar(4000),@7 nvarchar(4000),@8 int,@9 int,@10 int,@11 nvarchar(4000),@12 nvarchar(40),@13 datetime,@14 int,@15 int',@0=13,@1=0,@2=N'',@3=N'',@4=0,@5=Ncorrectemail,@6=Ncorrectemail,@7=N'',@8=0,@9=1,@10=0,@11=N'73.237.35.66',@12=N'268a0392-05de-4eef-b786-baf461f54566',@13='2023-06-01 22:40:54.767',@14=0,@15=-1

I believe this is a result of us setting the user first name and user last name as required.  This is DNN calling this when the user logs into the system.  I dont know where DNN is getting the ''.  The user names are correct in the users table AND the userprofile table.  If I leave the users table blank, DNN will update the userprofile table to blank as well.

Has anyone seen this?  I found this

With the same issues, but NO updates as to what it was.  

Any help would be appreciated.
