Please point out the possible issues. I made a test upgrade of my journal from OJS 2.4.4.1 to 3.0.2.0 following the upgrade guidelines. Upgrade has completed successfully. But the journal (test) page is not loading. The following is the list of error messages:

Please help to solve the issue. Thanks!

Solved the issue by changing the php error_reporting values…

Old value:
error_reporting = E_ALL & ~E_NOTICE

New one:
error_reporting = E_ALL & ~E_NOTICE & ~E_DEPRECATED & ~E_STRICT
