can't logout, reload page

okay so this will seem like an old question, but here we go:

I for SOME REASONE recently decided that I wanted to add a date row to my users table in my users database. (this is the db from ben rowes article on membership and whatnot). OKAY so I thought, well it should go after userId, it would jsut be easier to remember this way. After I changed every page that referred to the users table, I realized that $details[1] used it, for login purposes and I don't understand much of those early pages... anyway, I fixed the table so username is still right after userId (ie the first row), and then fixed all my variales back. But I still could not login properly, so I took the source files from the articles, and fixed a few things such as layout and links... but here is where I get my problem now.

whenever I try to login, with no info on my computer or in db's, it works fine. But then I try to logout, it lags up, and won't load the page. And i checked my db's, and found this in my online table:

id userIP dateAdded userId userName
658 127.0.0.1 20030624135810 0

there is no user id or username in my online table. I don't know if this happened before, but I doubt it, and I think this is causing the problem.

So where is this set? I can't seem to find it or find any problems. Does anyone have any ideas?
thanks

I figured it out, it was not deleting the cookie when I logged out. bah
