the fonts problem is extremely strange. after you vote for a site, for some reason the script sticks <div align="center"> at the beginning and </div> at the end, and that messes up the font sizes. i have no clue why it does that. it doesn't do that on my list. did you modify any of the .php files? do you remember using <div align="center"> in your templates anywhere?
as for the database not selected error, i didn't see it. maybe your host was having some problems with your database? their browser would not effect it.
