I continue to receive this error, even in pages where the certificate should be correct (https://anobii.com/login, https://telepass.it/AutostradeETIWeb/base/ETIScegliPercorsoUser) and where nor chrome or explorer show the error. I already deleted the file cert8.db but the problem persist.

How can I solve it?

Does this site work with a www. prefix?

The www.anobii.com server seems to be missing the intermediate certificate (RapidSSL CA) that is required to build a certificate chain that ends with a built-in root certificate.

You can download and install the first certificate from this site:

You can Copy and Paste the certificate text of the intermediate certificate to a .cer text file and import the certificate in the Certificate Manager or via Firefox > New Tab > Open File.
DO NOT set any trust bits, those are only required for root certificates and should never be set for intermediate certificates.
