SSL certificate strange work?

Question

Browsers

A certificate from rapidSSL was connected to the site. On a particular page, the certificate gives information differently depending on the browser. In chrome it is fully encrypted, in firefox and ie9 it is only partially encrypted and an alert appears with a warning, which is rather unpleasant. Why is that? How to find the error and eliminate it?

Answer 1

A warning that it is partially encrypted usually occurs when there are external objects on the page (images, banners, counters, frames, etc.) from third-party resources via http.

Answer 2

You didn't include the certificate chain.
If nginx, then you need to put this chain in the same file where the certificate is located. For other web servers, google for "soft_name cert bundle"
