Store is broken.

I wanted to purchase a starter kit but i cannot checkout. On clicking checkout i am redirected to a blank profile page.

If you're going to cross-post to the forum and GitHub issue tracker you should at least post a link to the other one:

That way people won't waste time trying to help you here if there has already been an answer there, also if someone else encounters the same issue it can help them find the solution or more information.
