If you are receiving warnings or even errors about your homepage being accessible both via domain.ext and domain.ext/index.php, there are two solutions:
Add to your header file, or to your index.php file the following snippet:
<?php $cpage = $_SERVER['REQUEST_URI']; if($cpage == '/index.html' || $cpage == '/index.html') echo '<link rel="canonical" href="http://www.butterflymedia.ro/" />'; ?>
This way, Google (and the other search engines out there) will consider both your root domain and your specified search page as one canonical URL link.
The second solution is using .htaccess (if available) to redirect index.php to root, like this:
Options +FollowSymLinks DirectoryIndex index.php RewriteEngine On RewriteBase / RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.php\ HTTP/ RewriteRule ^index\.php$ http://www.yourdomain.com/ [R=301,L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L]
