I'm having the same problem. OK, maybe it's because I'm frustrated but I'm going to need more explicit/specific instructions to solve this problem.
Opened up the wp_users table, deleted my password from there, got a new hashed password from http://bfl.rctek.com/tools/?tool=hasher
put that into the password field, and now I am back in :)))
Ok I don't understand exactly. Where is the wp_users table? You're not talking about the users.php file in the admin folder, are you?
I was excited because the install went w/o any hiccups, looked good, then I went to add a post saying such, and now I can't get in...
I really need to be working on my MA thesis, not this. Any help would be appreciated. But like I said, I'm fried. So please no assumptions, please be as explicit as possible with your instructions. Thanx again.
