When I go through the install, I leave the default en selected and click Next.
After the install, There are 2 languages that show up in the preferred languages section that is en and en_us. However when I switch to en_us, nothing happens even after purging cache.
But if I copy my lang/en_us folder into moodledata/lang/en_us and purge cache it all of a sudden starts to work.
What is the deal with the moodledata directory, why won't it work with the primary lang/ directory?
