Just for those people who are desperately trying to figure out what happened after they upgraded and PHP will not work.
From the /etc/apache2/mods-enabled folder run the following commands
Code:
/etc/apache2/mods-enabled# ln -s /etc/apache2/mods-available/php4.load
/etc/apache2/mods-enabled# ln -s /etc/apache2/mods-available/php4.conf
