If you want index.php to redirect to the domain root like me, but still want your highscores to save, you need to remove anything that redirects your index.php from .htaccess currently, then add:
Code:
RewriteCond %{REQUEST_METHOD} GET
RewriteCond %{THE_REQUEST} "T /index.php"
RewriteCond %{QUERY_STRING} ^$
RewriteRule .* http://www.yourdomain.com/ [L,R=301]
This will 301 redirect index.php to your root while still allowing the arcade to use index.php.
