Ah, so it is now for me, too. ^^

Oh, sorry, that 500 error is because I messed up while creating a theme, and I had to go and change it manually in the database. Instead of typing 'main', I typed 'Main'. Took me forever to figure out what I did lol. It should be working now, and I just got someone else to make me a theme, so I don't muck it up again. ;)
