I was getting a blank front page and had to disable all plugins (in safe mode) to get the site to load at all. I do weekly updates at around 9:00 UTC on Mondays and this was an extra update to fix the signature verification issue. However… there were quite a lot of other changes picked up as well, of course. And the version bumped to 2.9.0beta3 in that period, too.
As you will already have seen (but maybe somebody hasn’t), here is the diff for Discourse Encrypt between the version I have running now and the latest version as of this message.
Also, it didn’t really take until almost 4am to fix. It was all fine shortly before 2am, but then I had to tell people what had happened (most of our users are in the US).
