I just updated my Discourse at gradientdescent.co the same way I always do. (Edit: That is, via the one-click browser upgrade.) There was an error during the 2.4.0.beta8 update. It didn’t complete the first time I attempted the update. I tried it again and the update said it completed successfully, …

In the console, I did: cd /var/discourse git pull ./launcher rebuild app That fixed it. The site is up and running again.

2.4.0.beta8 update gave me the white page of death
