I am trying to update from ojs-3.1.2-4 to 3.2.0.3 and i get this error
A database error has occurred: Duplicate column name ‘email_id’
please, help me
Hi @Pradip_Dhakal,
Did you attempt to run an upgrade again after a failed upgrade, without first restoring your database from backup? That’s the most likely cause of this message.
