After upgrading from OJS 3.3.0.15 to the latest OJS Version 3.4.0.4, I received an error:
Errors occurred during installation
- A database error has occurred: SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name ‘current_issue_id’ (SQL: alter table
journals
addcurrent_issue_id
bigint null)
Column current_issue_id exists, and I do not know how to continue upgrading. Any idea?
Thanks!!!
