Old stuff just in case

To associate a certificate with a site:

1. Navigate to the My Media Sites page and select the site.
2. Open the Certificates tab.
3. If a certificate is already associated with the site, unlink it before trying to link a different certificate to the site. If your site is live, the changes won't be activated until you republish, so there is no need to worry about a lack of coverage.
4. Select Associate Certificates.
   The Associate Certificate dialog displays the list of certificates uploaded by users in your organization.
5. Select the certificate you want from the list, and then select Associate.
   The certificate appears in the table on the Certificates page.
6. If your site is already live, republish the site to activate the linked certificate.
