I’ve been running into issues trying to run a restore on our Staging Discourse instance. Staging is running v2.4.0.beta1 +36 . Any idea where the breakdown might be or where to look? Thanks in advance! Below is the end of the log output: [2019-07-16 20:08:12] ALTER TABLE [2019-07-16 20:08:12] ALTER…

I assume you already did it in app.yml then. Are (new) uploads working correctly? If so, then there is no issue.
