Directory index forbidden by rule

One of our client installed joomla successfully, and tried to access the administrative URL:: http://www.domainname.com/administrator/ and  got an error.

While checking on Server error logs it displayed:

[wpfmb type=’error’ theme=2][error] [client XX.XX.XX.XX]Directory index forbidden by rule: /home/user/public_html/domainname.com/administrator/[/wpfmb]

This error normally occurred due to multiple index files in the “administrator” folder.

Follow the steps in order to remove the error.

Go to directory:

cd home/user/public_html/domainname.com/administrator/
[root@server administrator/]# ls -l index*
index2.php
index3.php
index.php

Open the .htaccess file for the directory and mention the index file to be used.

vi .htaccess

Insert following line:

DirectoryIndex index.php

Save the file.

Try to access the URL now. The error should now be sorted out.
