After updating libapache2-mod-fcgid my websites won´t work anymore.
I found the following error in apache`s error.log:
[Sat Oct 12 09:33:53 2013] [error] (13)Permission denied: mod_fcgid: couldn't bind unix domain socket /var/lib/apache2/fcgid//15907.67
[Sat Oct 12 09:33:53 2013] [warn] (13)Permission denied: mod_fcgid: spawn process /srv/www/php-fcgi-scripts/web319/.php-fcgi-starter error
The problem were the rights for /var/lib/apache2/fcgid. There the user was set incorrectly after the update. A simple chown wwwrun.www /var/lib/apache2/fcgid fixed the problem.
wwwrun is the user under which apache runs, www is the group. UID and GID were set for apache in /etc/apache2/uid.conf definiert.
