Well never had a need to use it until now but for some reason the following is rewritten under forum index rss. https://beta.canadiancorvetteforums.com/forums/-/index.rss This is on XF 1.5 + xfmg 1.1. It's my staging/beta site. I don't think it's an addon or style issue as I've disabled all addons + tried default style to no avail. The URL obviously ends in a 404. Using nginx 1.9 + mariadb 11.1 + php 5.6. I'm using bog standard well documented nginx locations block for the XF install (double checked here). RSS is not cached either. Ideas appreciated.
