It's normal, you go to http://subdomain.domain.com/login, get redirected to http://subdomain.domain.com/index.php/login, then to http://subdomain.domain.com/index.php/index.php/login and so on because you RewriteRule always match.

You can write `RewriteRule ^([^/]*)$ index.php/$1 [L]

Make sure Apache rewrite module is active and your .htaccess file has the following line before any rewrite rule:

RewriteEngine On

Assuming you have mod_rewrite enabled, your RewriteRule causes an infinite redirection loop, which exceeds the maximum number of redirects and causes an internal server error.

You need to condition your rule so it only rewrites once. For example, this should work:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php/$1 [L]
