WordPress MU

Hi all,

I think i might be overlooking something obvious, but when i log in as a test user the language is still En and not the custom language.

For admin it shows the custom language. I have set the language under
Settings >> General
and
Blogs >> options >>Site Wide Settings (These settings may be overridden by blog owners)

btw: i can't see the option language setting when i am logged in as a test user.

Any tips?

Afaik, the Site Wide Settings will only be in effect on newer blogs. (edit: tested and this is the case for me) Did you create a new test blog, or did you just login as a user? Does this user have the ability to change the blog's settings?
