I’m trying to upgrade from OJS 3.1.2 to 3.2.0-3, and followed carefully (or so I think) all steps outlined in https://github.com/pkp/ojs/blob/master/docs/UPGRADE.md.
However, when I try to complete the upgrade, there is no “Upgrade” link as stated in the step “Select the “Upgrade” link and follow the on-screen instructions”.
It shows me what appears to be an installation-from-scratch page, asking for user admin name, database credentials, etc.
If I try to go on with that and put my existing username and database credentials (unchecking the option to create a new database), it gives an error:
This page isn’t working
revistademorfologiaurbana.org is currently unable to handle this request.
HTTP ERROR 500
Any help would be very much appreciated.
