Charles Error Please help me

every time i open my charles and goto ninjasaga the firefox say -->

This Connection is Untrusted

You have asked Firefox to connect securely to apps.facebook.com, but we can't confirm that your connection is secure.

Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.
What Should I Do?

If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.

apps.facebook.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is not trusted. (Error code: sec_error_untrusted_issuer)

how to solve that issue? please help me i want to use charles to ninjasaga again

please reply anyone please!

I have a question. Are you sure Charles Certificate installed on your machine? If not, try to install it (Google it how)

Can someone also help me?...

This error I've been having for atleast 2 weeks with charles but can't find anything on google.

[Only registered and activated users can see links. Click Here To Register...] uses an invalid security certificate. The certificate will not be valid until 28/08/2014 10:00 AM. The current time is 24/11/2014 3:04 AM. (Error code: sec_error_expired_certificate)

How do I fix this?.
