That's almost surely an effect of relative URL references.

  As a general rule, avoid relative URL references to static
  content because with high probability that makes caching
  much more difficult.

  In your case, the relative URL references go through "document"
  which blocks Zope's normal acquisition because the remaining
  URL path is put into "traverse_subpath" and not looks up
  normally.

  Access them via absolute URL's and your problem will go away.

  If you really do not want to follow this advice, you must teach
  your script to deliver the correct objects when they are
  referenced in the "traverse_subpath".
