This morning, my Discourse install just stopped rendering properly.
I took some pictures, but of course Discourse will not let me post them, because I’m a _new user_ and I could be **abusing the system**. So instead I’ll post them on imgur: [Blank Screen in Discourse - Album on Imgur](http://imgur.com/a/OSiFX)
I tried in in a few different browsers, Firefox, Chrome, Edge…
`ember_jquery` is throwing an `TypeError: e is undefined` error, which makes me think that some required file is not being loaded properly, but when I check the network window, nothing appears to be 404ing
I tried updating and rebooting Discourse, to no avail.
I emptied my Cloudflare cache.
I’m… not sure where to keep debugging from here.

I have a feeling this is the same issue as

> Ever since this morning my forum has only been showing a blank page on desktops, while being fine on mobile. On loading the site the console logs the following error: Uncaught TypeError: Cannot read property 'startRouting' of undefined at i.startRouting (\_ember\_jquery-60dedd1….js:2859) at i.didBecomeReady (\_ember\_jquery-60dedd1….js:3842) at invoke (\_ember\_jquery-60dedd1….js:337) at a.flush (\_ember\_jquery-60dedd1….js:405) at u.flush (\_ember\_jquery-60dedd1….js:529) at p.e…
Which was resolved by doing

> Yep, that solves the issue, particularly this setting: Forum started working again after I turned it off and purged the cache.
Also, I believe Cloudflare has been notified of this hiccup.
