Follow the instructions below to install your renewed SSL certificate and the certificate bundle on your Web server.
Before you install your issued SSL certificate you must install our certificate bundle (sf_bundle.crt) on your Web server. (You may also download the certificate bundle from the repository. The bundle is located in the Root Bundle section.)
Simply restarting Apache will not work. You must stop the service; then start it again to complete the installation.
