Hi, I've been getting the paizo error page pretty frequently lately. I was just able to recreate it in Firefox 48 and Chrome 52.0.2743.116 on Ubuntu 14.04.
Signing in takes me immediately to the error page. I can access the messageboards by going directly to secure.paizo.com/messageboards and it seems to work fine (including being properly logged in). Using the site-wide search crashes pretty frequently, but not always. I just tested with "asdf" and then "kobold quarterly" and the latter has crashed for me every time, but "asdf" worked fine.
Happy to post other info if you need it.
