Godaddy cPanel problem with .htaccess file

My website shows

Forbidden

You don't have permission to access this resource.Server unable to read htaccess file, denying access to be safe

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

The .htaccess file was found empty. My site include both html and php file so I rewrite the .htaccess as follows:

RewriteEngine on 
RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_FILENAME}\.php -f 
RewriteRule ^(.*)$ $1.php

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.html -f
RewriteRule ^(.*)$ $1.html

But it doesn't work. Please help me fix. Thank You
