We recently went from a standard SSL certificate to a wildcard one. We use RapidSSL for our certificates. As of Firefox 23 we are getting the following untrusted connection error:
www.safelincs.co.uk uses an invalid security certificate.
The certificate is not trusted because no issuer chain was provided.
(Error code: sec_error_unknown_issuer)
I looked in to this and believed it to be a missing intermediate certificate, so I went to the RapidSSL support page and downloaded the primary intermediate certificate (crt) then added the following line in to the apache config.
After restarting apache successfully I ran an SSL check. The path is as follows:
*.safelincs.co.uk -> RapidSSL CA -> GeoTrust Global CA ->Equifax
I thought that this would have fixed the problem, but I am still getting the error when I visit the web site: https://www.safelincs.co.uk.
I'm no expert, obviously, but can someone please point me in the right direction? This is only happening with Firefox 23 so far that we've noticed, but it's a big issue as that makes a large percentage of our sales customers.
