Also I would have upgraded in steps. I never recommend doing more than one LTS worth of jumps at a time. When you Start jumping too many versions weird things can start happening.

Yeah, that seems to happen on occasion with old LocalSettings.php from
previous installations. We have experienced it several times because
we started our wiki in 2005 or so.

One other thing you should be sure to do... run 'php
maintenance/update.php' after each upgrade. If the database changes,
then update.php is what handles the changes for you.
