You may not have the Options directive configured correctly for that folder. To enable for just that folder, you can drop an .htaccess with the following in that folder:

check your access permissions on the directory, they should be something like this:

• Numerical: 0755
• Flags: DRWXR-XR-X

Edit: From your screenshot, it looks like you've got some kind of authentication module (mod_auth_passthrough).. you might check to make sure it's configured properly.
