Directory index forbidden by Options directive June 8, 2009

I was going through error log and saw this error in error log file. To solve this problem, 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>

Just remove the hyppen(-) before the Indexes, that’s it. I hope this will solve your problem.
