When I try to follow the "Frequently Asked Questions" link on this page:
https://paizo.com/pathfinder/rpg
which I believe leads to:
https://paizo.com/pathfinderRPG/faq
the page content never loads, leaving just a header. It actually looks like the page is repeatedly reloading itself.
I was able to reproduce this problem.
The first time I tried, the page prompted me to log in and took me to the proper FAQ page after I did.
The second time I tried (being already securely logged in), I got exactly the same result that Callum did.
