XF 1.3 Facebook / Twitter register options generate 404


Active member

I'm having an issue with the built-in options for Facebook and Twitter registration. When clicked, they just bring up a 404 page.

You can try them on my site here: http://forums.exophase.com/

I'm running nginx 1.4.7 and PHP 5.5. My first guess at the culprit was the rewrite settings for nginx - but they match what's mentioned on the XF help page.

location / {
index index.html index.htm index.php;
try_files $uri $uri/ /index.php?$uri&$args;
Here's the error I see in raw server logs, nothing is generated on the XF side. I removed some data from the link.

x.x.x.x, server: forums.exophase.com, request: "GET /register/facebook?code=longstringoftexthereHTTP/1.1", upstream: "fastcgi://", host: "forums.exophase.com", referrer: "http://forums.exophase.com/"
Any help is appreciated.
