accessing subdirectories on server

[micahpage]

when i try to access any file in a sub directory of /var/www from the browser i get an error. I sometimes get a permission denied or this:

[an error occurred while processing this directive]

not sure which makes the difference.

What can i do to make sub directories of /var/www accessible?

i tried this but it did not do anything

sudo chmod a+x /var/www/test
