LinuxQuestions.org - setting local settings fails

Hi everyone.

I have a Debian server I hire from a hosting company, that installed Debian in German. I could however change the language to English, but now I'm getting this error from logcheck (every hour in my mailbox). Some commands also return in unreadable errors (like in squares), probably a wrong character set.

I tried:
export LANGUAGE=other_language
export LC_ALL=other_language
dpkg-reconfigure locales

somehow it never accepts the changes. Do I have to (re)start any service or program after dpkg-reconfigure locales or export LANGUAGE? Or do I have to edit a file/download a package? I just want US English as language.

thanks in advance!
