I've successfully created my first C5 site for a client, which is awesome. However the client has the same business in another country and rightly asked if I could port the same site to the other country which I did with no problem, until now.

Next, the client wants to make some pages on the new site SSL which in theory should be easy right?

First, I got the client to by the SSL cert, which is done, then I simply installed the "force SSL" add-on which I did and applied to the said pages, and I thought it was all working.

However on closer inspection, when I typehttp://domain.com the site simply redirects to the http - non secure connection, so I can't even view the site with https.

I know the https is working because I placed a test.html page on the server in the same folder as the C5 install and this does load as https.

All the theme files use "$this->getThemePath() . '/style.css'"

I've tried, changing the site.php to:
<?php
define('DB_SERVER', 'servername');
define('DB_USERNAME', 'name');
define('DB_PASSWORD', 'password');
define('DB_DATABASE', 'dbname');
define('BASE_URL', 'https://domain.com');
define('DIR_REL', '');
define('PASSWORD_SALT', 'uqCwl8hwDLu4eusDbYgR7KTkf9aQmjcYxbFkBYMiGth3P2zS84SZyvJyWHRn2v5a');
?><?php define('REDIRECT_TO_BASE_URL', true); ?>

site won't load

and

<?php
define('DB_SERVER', 'servername');
define('DB_USERNAME', 'name');
define('DB_PASSWORD', 'password');
define('DB_DATABASE', 'dbname');
define('BASE_URL', 'https://domain.com');
define('PASSWORD_SALT', 'uqCwl8hwDLu4eusDbYgR7KTkf9aQmjcYxbFkBYMiGth3P2zS84SZyvJyWHRn2v5a');
?>

the site doesn't work at all

I've tried other combinations where I get "Firefox has detected that the server is redirecting the request for this address in a way that will never complete."

I must be missing a few brain cells here? is there something that needs to be changed in the database?

Any help would be greatly appreciated!
