OJS 2.4.8 to 3.2.1-5 ERROR: Upgrade failed: DB: Column ‘publication_id’ cannot be null

ERROE:Upgrade failde:DB:Column ‘publication_id’ cannot be null

Hi @LiM,

Have you checked existing forum topics on this issue?

Regards, Primož

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.
