Hello, just wanted to share that I get the same database as @potravinarstvo in the final step of upgrading from OJS 3.2.1.2 to 3.3.0.3 via Softaculous:
A database error has occurred: SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘url’ in ‘field list’ (SQL: select url, navigation_menu_item_id from navigation_menu_items where context_id = 1)
I am adding to this thread to follow and help troubleshoot this issue. Thank you!
