Hmm, who is Daniel?

Do you get certificate errors on any other mainstream websites, or only on this particular Facebook app? You should never need to make an exception for a well-run site.

We do have a support article related to that error code. In case you didn't see it before: How to troubleshoot security error codes on secure websites.

Does anything there help? If not, we can try some additional troubleshooting.
