Hello! On my ubuntu server I play with vBulletin-to-Discourse migrate process.
Itself migration was did well, and I start for bbcodes adapting. Before apply next patch to raw text(with **rails c** regexp), i did backup from admin web-panel of my discourse.
Later i found some bug in my regexp and decided to roll back to the previous state(restore from my backup). And now(after restore), then I try to rebuild post html, I have 500 server error
and at the same time in logs:
```plaintext
RuntimeError (Undeclared attribute type for enum 'status'. Enums must be backed by a database column or declared with an explicit type via `attribute`.) app/models/post.rb:818:in `rebake!' app/control
```
Same error appear in logs, as I understand, caused of Sidekiq jobs.
May be someone faced with the same error?
I was try to repeat restore, with the same result.
And ofcause I was try to reboot my server.
Try “[Safe mode](https://meta.discourse.org/t/53504?silent=true)” too… 😔

Did you ever figure this out?
I’m having a similar issue after attempting an update, and then a rebuild of the container.

Thanks for the quick reply; that’s not an option for me so I’ll seek some further help.
