I found a problem while I upgrade OJS. The error code shown below.
- A database error has occurred: SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name ‘email_id’ (SQL: ALTER TABLE email_templates_data ADD email_id BIGINT)
I found a problem while I upgrade OJS. The error code shown below.
Is this the first attempt to upgrade, or was there an interrupted attempt, and you tried again without restoring the database backup?
Also, are you upgrading from which OJS version?
I am also having that problem, for me there was an interrupted attempt and I don’t have the backup database so how can I fix this
Hi @Pee-Kay,
I see you’ve opened a new topic about this – it’s best just to post in one place. I’ll close this topic and continue the discussion over there.
Thanks,
