  • Be sure not to include any illegal characters in any of the fields of the CSR. Illegal characters are [! @ # $ % ^ ( ) ~ ? > < & / \ , . " ']

"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 * , you have to install it on each subdomain such as,,..etc. Use the same certificate for each subdomain you install. Good luck!"
