Activating SSL Certificate Support in Magento

Once you have purchased and had your SSL certificate installed you then need to enable its use within Magento. The procedure is as follows :

1) In your Magento Admin Panel navigate to System -> Configuration -> Web -> Secure
2) Ensure the Secure Base URL is using https and your certificate's Common Name (e.g http://secure.nublue.co.uk/). Don't accidentally delete the trailing / , your site will not display properly without it!
3) Enable Use Secure URLs in Front End and Use Secure URLs in Admin Panel
4) Save the configuration.
5) Refresh the cache and test!

Note

If on Checkout you get an unsecure content / partial encryption error then the probable cause is that your web page is pulling in object(s) using http instead of https. The most common culprits are hardcoded full URLs (as opposed to relative URLs) in the css or templating.
