Forum upgrade / users logged out
I have updated the forum software. There was a recent regression in the software in the TTL for session storage, meaning old sessions were not removed (ttl was 14000 days instead of 14 days). This meant we had 1.8gb of memory in usage for session storage (5.8 million sessions), and it was causing low memory issues on our server.
I have updated to the latest forum software which has the bug fixed, but I had to clear out all the old session data, which means you will need to log back into the forum again on your devices. Performance may also now be improved, as the redis cache is no longer utilising swap space etc.
Apologies for any inconvenience.
