I followed the upgrade guide localed at: Upgrading - Omeka Classic User Manual but give the error: “Error SQL en la migración.Mysqli prepare error: Incorrect TIMESTAMP value: ‘0000-00-00 00:00:00’”
I follow the steps:
- Change the name of the original Omeka folder to “omeka_old”.
- I donwload the lastest version of Omeka and extract to “omeka” (the original folder/URL of the installation)
- I do the point 5, move the files and directories indicated from “omeka_old” to “omeka”
- Try to upgrade the DB using: /omeka/admin/upgrade but fails with the error described.
