For the last few days I've been noticing that the "page loading" indicator for any page on the Paizo site keeps going for a long time after the page is apparently loaded. Further investigation has revealed that the pages are trying to load this file:
... but that subdomain is not responding to requests. So the loading indicator just keeps going until the connection times out.
While I'm here, I noticed a couple of other errors while I had the JS console open:
Blocked loading mixed active content “http://paizo.com/include/fonts/OpenSans-Regular/OpenSans-Regular.woff”
Prob ably means you've got a hard-coded HTTP somewhere which needs to either be HTTPS or else be protocol-relative (which has downsides of its own).
ReferenceError: invalid assignment left-hand side in paizo-libraries-min-003.js
Since that's minified code I don't know that I can give you much more useful detail than that, but it appears to be something that's called when someone is creating a new post.
