Community Homepage not loading after updating text.

Hello, 

I was making routine edits to our site: (+) AD Connect (ad-datainitiative.org), updating some text in a callout box, when suddenly the homepage stopped loading properly and shows as a blank page underneath the nav bar (see screenshot below). I don't see any unusual errors in our site monitoring. Has anyone had this issue before? 

And can you recommend any methods to get it fixed quickly as traditional support channels are taking a bit longer than I expected to fix? This is urgent for us as our users cannot access our community homepage. 

Thank you.
