I am upgrading from PKP 2.4 to 3.0.2 on Ubuntu, MySQL 5.5.
I followed the full package procedure. The upgrade command completed with no message.
When I access the website, I get the following screen:
DB Error: Unknown column ‘context_id’ in ‘on clause’

After the failure, I upgraded to MySQL 5.7, but with the same result.
It seems somehow related with the plug-ins.
We had installed very few plugins (e.g., Crossref). But, since some time, on the production server, the System plugin page cannot be loaded. So there could be an issue there.
