What ever the issue was, it seems like the user did not get the userid assigned to them properly.

Make sure you get rid of all the files that came with Inferno Shout from the server as well, if there were any to load with the mod.

Make sure the user has a record in userfield table ..

Don't matter, the user has been banned and asked to create a new account. :)

For future reference, you could have tried Maintenance > General Update Tools > Fix Broken User Profiles :)

I thought about that Lynne, but the users profile was not broke, it was that the userid was not fully assigned to the user somehow. So by looking for the user in the ACP, he would not show up. Clicking on the users name in List New Registrations would lead you to a profile page in the ACP, but no fields filled out.

Did you take a look at the database? When a user is registered, the userid gets put in several different tables. You can still view some things like the profile, or the user in the admincp if only a couple of tables are filled out. But, you will have other things broken if not ALL of those tables have the information in them. It just would have been worth trying.

No I did not, I did not have access to the DB. But the OP just banned the member and asked him/her to re register.

i checked the database the users have the same fields like all the other users.

Which specific tables did you look at?
