Certificate is not signed by a root certificate
When the SSLCheck gives an error that the certificate is not signed, a self-signed certificate is active on the server.
A self-signed certificate secures the connection with SSL. But because the certificate isn't issued by a Certificate Authority (CA) that's trusted by the browsers an error is displayed.
When a certificate is purchased and an error is given, the certificate isn't installed properly. Manuals for the installation can be found in our knowledgebase. It's possible to contact our supportdesk as well.
