Root Certificate Installation

The Issuing Authority's Root Certificate will very likely have been installed into Opera along with your own certificate.  This root certificate is required by Opera in order to trust certificates issued by the Issuing Authority (including your own).  If you cannot find the Issuing Authority's root certificate in your "Signers" store, it may not have been supplied with your user certificate.  In that case, you need to go to the Issuing Authority's web site and download the certificate from there.

At the Issuing Authority's web site, there should be a clearly labelled link that enables you to download the root certificate.

Highlight the appropriate Authority and select the "Install" button.

You will be asked to confirm your selection to install the Authority certificate. Click "OK" to continue.

The certificate for the selected Authority is now installed in your browser.

If there were multiple Authority certificates you will need to import all the certificates in the chain. Repeat the process and select the other required certificates.
