I am having a similar problem with importing users. I can import users just fine. (I created my own import script to import users from another MySQL database.) The login works for the user account and I can log in as a test user and can edit the user profile (logged in as the user). The users also show up in the "Member List".
My problem is that users are not showing up in my Joomla Admin.
My problem is with the "CB User Manager" screen:
administrator/index2.php?option=com_comprofiler&task=showusers
AND
The "Standard User Manager" screen:
dministrator/index2.php?option=com_users
Not all of the users are showing up here. Right now I have 8 test users in my db (1 admin and 7 test users).
In the User Manager screen the "count" shows "Display #30 Results 1 - 8 of 8", but only 4 users are being shown?
There seems to be something "funny" going on as it relates to the "User ID's" in the db and how the User Manager is sending a query to the database to display users. Something to do with the AutoIncrement id?
In my custom import script I "assign" a new user ID and do not let the db auto_increment it.
I am trying to find the SELECT query, for the User Manager screen, but have not been successfull so far.
Thanks,
Neal
