Do you have external resources included in your course and your LON-CAPA
server is ssl encrypted?
Then you should consider that Firefox as of version 23 (current version
24.0) blocks mixed content. This results in an empty page in your course
by default if you access your server via https and the external web page
is accessed via http.
It is possible to temporary disable this blocking by clicking on the
shield icon left to the URL and choosing disable blocking.
