Layouts works only if you logged in

So everything looks broken. How do I fix this?

Not impressed.
Go to your cache settings in System & Settings and turn block caching off completely. For some reason the block caching seems to be breaking both blocks and layouts right now.
It worked for me. Good luck, folks.
