Please be sure to include the header and footer as well as the surrounding dashes. Do not use Microsoft Word or other word processing programs that may add characters. Confirm that there are no extra lines or spaces in the file. Save your certificate with a .p7b extension.
Note: If the PKCS7 format is not used, the Intermediate CA certificates MUST be installed separately using these steps
Step 2: Install SSL certificate
Step 3: Verify certificate installation
If you do not specify an IP address when installing your SSL Certificate, the same certificate will be used for all virtual servers created on the system.
If you are hosting multiple sites on a single server, you can specify that the certificate only be used for a particular server IP address.
