VBuletin shows bare skeleton as home page

Thank you, I remember doing that years back with .htaccess file. Now, my .htaccess looks like this (autocreated when I blocked 3 IP addresses using cPanel that my provider gives).
What should it look like after the change you are telling me?

<Files 403.shtml>
order allow,deny
allow from all
</Files>

deny from 77.78.208.0/20
deny from 217.182.0.0/16
deny from 51.254.0.0/15
