Questions:

1. After the upgrade to 7.3.1 if I go to Control Panel > Languages there is no language listed (I expected English). Shouldn't English be listed? How do I resolve this?

2. If I click on the "Language Editor" tab there is nothing in the pull-down. If I choose "Choose Specific Language File:" and choose "admin/languageeditor.php" (or really anything) and click "Go" I get a white screen. How do I resolve this?

My upgrade was from 7.2 to 7.3.1 and it went smoothly.
