Apache CentOS5 - Directory index forbidden

[Apache + CentOS5] –  Directory index forbidden by Options directive: /var/www/html/

I was having the same exact problem as you, this is what fixed “/” directory listings for me

In /etc/httpd/conf.d you will see a file entitled welcome.conf

It looks like this:

<LocationMatch “^/+$”>
Options -Indexes
ErrorDocument 403 /error/noindex.html
</LocationMatch>

Change it to this:

<LocationMatch “^/+$”>
Options Indexes
ErrorDocument 403 /error/noindex.html
</LocationMatch>

All we actually changed was the hyphen in front of Indexes. This worked for me, hopefully it works for you.
