Current install is: 2.7.0.beta1
The server has a complicated history (it’s about five years old) and was a standard install self-hosted, then transferred to Discourse hosting, then transferred back - we’ve tried to keep it as standard as possible.
I am pretty sure it’s the current version.
The server has had intermittent outages/stalls etc which have been effecting performance and may have been impacting the database. List time I did a database clean-up it shaved a lot of data out of the postgres file.
Currently the backup file I do have access to is 1.5 gig, so has been too large to edit with any software I have on my PC currently.
There are other issues I am aware of where trying to migrate images to S3 has failed etc, but previously there were no issues with backups etc.
