We’ll give the upgrade new try tomorrow. I’ve had some good input from admins of other instances, which are also gonna help troubleshoot during/after the upgrade.
Also there are newer RC versions with fixed issues.
Be aware that might we need to rollback again, posts posted between the upgrade and the rollback will be lost.
We see a huge rise in new user signups (duh… it’s July 1st) which also stresses the server. Let’s hope the improvements in 0.18.1 will also help with that.
Hopefully third time’s the charm and the upgrade will be successful.
Most issues were caused by browsers trying to access cached code. A recent change introduced changed paths for each new release, so browsers will fetch the new files. At least those issues should be a thing of the past.
