Sites not displaying php files, but show the code instead.

Hello, I'm running redhat 4.0 AS server with Apache and php. I have a few sites that have index.php as their DirectoryIndex. When I view those sites, I see the php code, not the page as it should be. Also, there are a few sites where index.php is actually a symlink. For those, I get this when I go to the site: Forbidden You don't have permission to access / on this server. Any ideas why this is happening? -- Jody Cleveland Computer Support Specialist cleveland@winnefox.org
