It was a strange solution, but atleast it worked/

For anyone who runs across this topic from a Google Search, and if it doesn't address your issue...

The problem I was having was that I setup a PHP/apache redirect so that any attempts to access my domain would be redirected to the www version.

However, I didn't properly update Settings.php to match (i.e. to use the www) - I didn't realize there was a setting for it.  This resulted in any attempts to login showing the "You need to fill in a username." message.

Hope that helps anyone who runs into this (I ran into the problem on GoDaddy hosting)

Thanks for these postings. I have a new installation and got the same error message. After an hour I managed to resolve it via this post and others.  The most helpful was the repair tool at http://wiki.simplemachines.org/smf/Repair_settings.php. I wish I had found it earlier!
