Hello,
I have a single journal OJS installation migrated from OJS2 to 3.1.1-4.
Generally speaking - things are working fine (despite plenty of problems with database encoding) but I’m seeing some PHP warnings with debugging switched on and I would like to know if they should be addressed or can be ignored?

I’ve upgraded the system via a command line using fresh OJS files so there shouldn’t be any leftovers from older versions.
