dev.gentoo.org's web server seems to be configured for content negotiation, but is missing Finnish (.fi) from apache's configuration. Please add "AddLanguage fi .fi" and proper LanguagePriority setting to apache's configuration.
Done, double check and close if its working.
Seems to work for me. At least the address given in URL field correctly negotiates both Finnish and English: marking verified. Thanks.
Just noticed the current dev.gentoo.org is back to not recognising .fi suffix, reopening.
woodpecker-admin, please check.
all done
