I decided to upgrade to Mavericks today. Things went pretty smooth, right up until trying to continue work. I don’t use Vagrant or MAMP, but rather the built in Apache2 (with PHP, etc installed via Homebrew).
My VirtualHosts in /etc/apache2/extra/httpd-vhosts.conf
were kept, but going to http://localhost/ took me to the default “It Works!” page. I quickly discovered that the httpd.conf file was reset. Stuff I had to do to fix it below.
