ERROE：Upgrade failde:DB:Column ‘publication_id’ cannot be null
Have you checked existing forum topics on this issue?
hi,I have checked, but I have not found any problems related to my problem. Only problems occurred during the upgrade of Ojs 3.1. x to 3.2. x
I would suggest verifying the solutions. Might be the same problem, not related to the source version.
Thank you. I have successfully upgraded to version 3.3.0-13.
