I ran into the same issue today. However for me the issue was only brought to light when I had a second vhost that was doing modproxy. For some reason the modproxy usage in a separate vhost caused the AddTypes to stop working. After some research it appears that AddHandler should be used to enable mod_php. And indeed replacing AddType with AddHandler did correct the problem.
