[Solved - for the most part] Force admin console to use ssl?

[Andrew Prior]

I find if I do not comment out the old line $config['admin_dir'] = 'admin'; according to Edward's suggestion that things mostly work. I am getting another error I need to track down. But this is a beginning

I have my on ssl certificate which works fine for site readers, but I want to use it for my admin console.
I used this suggestion from Edward Robirds

Update

Since "Martinique" was released on Oct 22, 2011.... just update your "config.php" file to the following:

#$config['admin_dir'] = 'admin';
$config['admin_url'] = 'https://www.YOURDOMAIN.com/admin';

Obviously I have changed the domain name and the admin directory name to fit my own.
I also tried 'ssl_admin_url'

This certainly does not work for me at all, simply screens of errors... is there anything obviously wrong with what he suggests before I start posting pages of errors?
