Hello, I updated my server first to 3.1 then to 6.0. There was an only office upgrade in there also. The first sheet I opened after upgrade failed and returns an error now. All the other sheets opened ok although the new Home bar has most of the tools that were there before removed. It looks like the first sheet was corrupted and now I cannot access it. It is an important document. I have backups.
So I am wondering, if there is a way to fix this without a backup. Can I downgrade to the previous version of OnlyOffice (maybe it will open there)?
If the above 2 are not possible, how do I locate that particular file in the backup so I don't affect everything else on the server? I imagine the ref no. is in the url, but I'm not sure where that is stored. I see only double digit numbers in datastore and blob.
