This means that you're getting a CF error and FarCry is catching it. The
only way to see what the error is, is to put in the URL variable debug and
set it to true (i.e. domain.com/?debug=1).
Unfortunately FarCry catches most CF errors and there is no "setting" to
turn this off (most developers would rather have the user go to a "sorry
there was an error, but our dev team has been notified... etc" and have the
developers get a detailed error report). So we are unfortunately stuck with
waiting to hear from end users on large/massing sites for pages that are
"blank" (or check our CF error logs regularly). Or we can just "assume"
that our code is perfect 
.
So, yeah. Debug=1 will help you out there.
