I am using site "https://www.ultimatix.net" for learning purpose. This site directs to another site for web based learning, which is "icalmscontent.ultimatix.net". It is giving error "icalmscontent.ultimatix.net uses an invalid security certificate.

The certificate is not trusted because no issuer chain was provided.

(Error code: sec_error_unknown_issuer)", and there is no button to add exception. Please help.

hello nitin2joy, the "add exception"-button is not accessible on framed pages for security purposes (to avoid phishing/impersonating by malicious sites). in case the page you're trying to access is embedded in an iframe, right-click the error page, click on "this frame" > "show only this frame" and hopefully you can add an exception in the next step. this should only be necessary once if you choose to permanently store the exception.
