Thanks for this temp solution
In our testing, you only need to uncheck CSS.
Keep in mind this sets it so your entire domain isn’t auto minimizing CSS. You may want to create a page rule for your Discourse subdomain and add the rule “Disable Performance”. Keep in mind this turns off all auto-minify, Rocket Loader, etc ONLY for your Discourse subdomain.
I strongly recommend you check “Purge Individual Files” and then type in your Discourse domain with trailing “/*” (slash star). This way you are only clearing all cache on your Discourse instance and not your entire origin domain.
