I got it! Thanks for the support, everyone.
I did a full uninstall/reinstall. When I went to edit the /var/www/fog/commons/config.php file, I think I accidentally entered in the password in the define( "DB_PASSWORD", MYSQL_PASSWORD );
Then when I tried by making the fog db, it screwed everything up.
On an aside, is it okay to delete the default user now that it's installed and I created a user or is that a no-no?
I know some programs rely on the default user they create... and I just got this working; I don't want to break it already.
