Since yesterday, I have the strange issue that the dashboard in the browser is empty. Although, the CLI-dashboard just functions fine. No errors in the log altogether.
Please, search for “malformed” in your logs. I would prefer to have text logs instead of photo of the text, but, well… As pointed by @nerdatwork - you have at least one malformed database.
I would suggest to check all databases and fix corrupted ones, if you would like to have a working web dashboard of course.
I went through all databases, and they indeed turned out to be broken. Since my databases are in a snapshotted btrfs-drive, I recovered the last snapshot and it worked again like a charm.
