SO I messed up. I installed this plugin GitHub - LeoMcA/discourse-rss-poster: Discourse plugin which allows RSS feeds to post to the forum and it gave me a blank white screen. Now I have the same issues as this post I am getting white blank page after installing AdSense and Spoiler plugin
I removed the plugin from app.yml and rebuilt 2 times. then cleared cache. checked it was gone, rebuilt another two times. cleared cache some more and rebuilt then checked here and same issue. only 404 page works and everything else is white screen. Not showing any js errors. Anyone have another option or idea short of removing all the plugins? Everything was fine before.
