Our default 00_mod_status.conf for 2.4 has: Require host 127.0.0.1 But that got me 403s, the host directive does not seem to work with IP adresses "Require ip 127.0.0.1" works, though after checking http://httpd.apache.org/docs/2.4/en/mod/mod_authz_host.html, I switched my setup to "Require local" (works in ipv6 and other local adresses) 00_mod_info.conf has the same problem Apart from that, the 2.4 upgrade on my server went mostly fine :)
Thanks for the report: http://git.overlays.gentoo.org/gitweb/?p=proj/apache.git;a=commitdiff;h=fbdf004b77ec97b4df28e42d8038c07b87bd563f This will be in the next gentoo-apache tarball rollout. Please keep this bug open until a fixed apache is in portage.
Fixed in =www-servers/apache-2.2.27-r3 and =www-servers/apache-2.4.9-r3.
