I suppose you installed PHP as an Apache module...are you sure you did this?
quote:
Finally, search for "AddType" in the file, and add the following line after the last "AddType" statement:
AddType application/x-httpd-php .php
If you need to support other file types, like ".php3" and ".phtml", simply add them to the list, like this:
AddType application/x-httpd-php .php3
AddType application/x-httpd-php .phtml
