I moved to a new server - that wen't reasonably well... only a few issues with danish chars æøå/ÆØÅ. But after upgrading to 2.1.1 from 2.0.x on the new server localization stopped working!
Changing wp_lang setting i wp-config doesn't seem to have any effect. I've tried several different language .mo files - so the language files don't seem to be the poblem.
My setup is:
Wordpress version 2.1.1
php 5.2.1 (with gettext enabled)
No error messages to give me any clue. This is really annoying me... any helpful suggestions would be greatly appreciated!
