I have recently run into a problem updating my users. I try to change Role, Last Name, First name, even the avatar. I make those changes then hit Update User. It returns a message that says Update Successful, but nothing has changed. The information I entered is all gone. I'm not an experienced user. I have reinstalled the WordPress 3.1 a couple of times thinking that something may have not installed correctly. I've deactivated some plug-ins, still no change on the User Edit screen. If anyone has a suggestion, I would be greatly appreciated. I can send several screen shots if necessary.
