My view:

Answer 1

I had a problem that could very well have been the same.

I fixed it by taking out the byte order mark from the localization files.

Answer 2

Your locale data is for English (en) but your strings are, I think, Norwegian (no). What locale is your application running as? What language is your browser asking for? What happens if you add an no: section for the Norwegian?

As a wild guess I'd think that you application ends up trying to use the Norwegian locale but it can't find any configuration for Norwegian so it uses the hard-coded en_US stuff as a fallback. I'd also guess that everything works out on your machine because the default fall-back locale is no_NO; what happens on your local machine if you change the short date format in your en: locale section?

More guesses that answers here but this was a little too big and involved for a comment.
