Don't worry, there is an easy fix to that!
You can REDIRECT ALL http traffic to your https (SECURE SSL) files using a simple .htaccess file.
The instructions are in our other HELP ARTICLE:

Remember that you will always be able to access all your website files both NOT SECURE via http AND SECURELY via https.
Also, keep in mind that it will take some time for google to UPDATE their database and reflect your NEW SECURE SSL files, etc.
