I do not believe that the problem is an outdated CA or root certificate list. The web page referenced in the initial post of this thread was tested using the system browser and the page displayed (this should rule out the system certificates/CA). Mozilla Firefox 6.0.2 (same version that the version of Pale Moon I use seems to be based on) also successfully could browse to the page (this should rule out the Pale Moon browser certificates/CAs if it uses the same certificates/CAs as Mozilla Firefox 6.0.2 and those certificates are properly installed).

I tried setting rowser.xul.error_pages.expert_bad_cert to true as you suggested; however, the problem persisted.
Both Mozilla Firefox 6.0.2 and Pale Pale Moon 6.0.2 have browser.xul.error_pages.expert_bad_cert set to false by default.
Pale Moon 6.0.2 had app.update.cert.checkAttributes and app.update.cert.requireBuiltIn set to false (by default); I set the variables to true (the Mozilla Firefox 6.0.2 default), individually, and tested the web page referenced in the initial post to this thread, but the problem persisted.
