Over the weekend, php stopped working on our domain (zibal server). I know there was some change that is causing the AddHandler/AddType commands in htaccess to cause a 500 error. Unfortunately, I haven't been able to figure out how to change them in order to fix it. I've tried just about every combination I can think of. As I wait for 2nd level support to get back to me, our website, which depends entirely on php, is down.

This is what worked prior to this weekend:
# Use PHP5 as default
AddHandler application/x-httpd-php5 .php5 .php4 .php .php3 .php2 .phtml
AddType application/x-httpd-php5 .php5 .php4 .php .php3 .php2 .phtml

Does anyone have AddHandler/AddType statements that are working for php 5 that you could share? I'd like to give them a try.
