Re: CyberSource Invalid Field
You need to install an ssl cetificate if SSL is installed on your server. You may need to check with your hosting company to ensure that they allow this in your hosting environment. They will need to generate a CSR ( Certificate Signing Request) and tell you what type of system generated the CSR (Linux-Mod Apache) .
You can then go to http://www.instantssl.com or any one of half a dozen SSL certificate providers.
After you purchase you can wither bring it to your hosting company or if you have cpane; you may try installing it yourself.
Further than that would take a long time to type out.
