We are having trouble upgrading OJS 3.3 to OJS 3.4.01
The following error occurred:

  • A database error has occurred: Storage engine that doesn’t support foreign key constraints detected in one or more tables: pln_deposits, pln_deposit_objects, publons_reviews, publons_reviews_settings. Change to InnoDB before running the upgrade.

Please guide.
