Hi @Rohaan123,
Your database structure is currently somewhere between OJS 3.1.1-4 and 3.2.1-1, and unless you captured the error message you encountered when you first tried to upgrade, you won’t know exactly how much of it got adapted to the new structure. The only easy way to resolve this is to reload from a backup. If that’s not possible, I’m afraid I can’t walk you through this step by step. Essentially you’ll need to compare the data structures in your broken database against what’s supposed to be there in a clean OJS 3.1.2-1 installation. The upgrade process is scripted in dbscripts/xml/upgrade.xml, if you need to review the sequences the changes are made in.
