"Very fast delivery. Installation was easy with no problems. If you are installing a wildcard SSL certificate on cPanel, you need to specify the actual domain name, don't try to install it on *.domain.com , you have to install it on each subdomain such as admin.domain.com, shop.domain.com,..etc. Use the same certificate for each subdomain you install. Good luck!"
