Dear all, we have a new Developers Forum: http://helpers.pyxis.uberspace.de/profile/developers (the old one @Friendica Developers seems to be offline permanently)
A recent pull request to the “develop” branch introduced a nasty bug that blocked the background processing that is used to distribute messages, to import feeds and to do several more stuff. Please update your system as soon as possible if you are running with the “develop” branch and the “worker” background processing isn’t enabled.
