Flavors.me pages get horribly broken

When trying to visit the linked pages on https://flavors.me/layouts, the first 3 render horribly, and the 4th is stuck in a redirect loop.

Also, when logging into your own flavors.me account with Facebook, the page gets stuck on the redirect to your site just after logging in.

I'm using HTTPS Everywhere 2014.1.3 but I've had this problem for months.
