After a system upgrade I moved from Gramps 4.x to 5.1.3, and no more able to open my database.
(I know I should have made a xml backup)
I have an error message saying it could be an older format of database, or some corruption.
I checked BSDDB in gramps 5.1.3 and in my db, they are both (5,3,28)
I retrieved a db backup that was for sure not corrupted, and got the same message.
Has anyone any idea for proceeding? Is there still a compatibility issue?
Running Gramps v5.1.3 on Fedora 33
