Maybe, delete it or use temparary cache files.

Look into your ZServer log file (usually called "Z2.log"):

  Do you see your "manage_menu" request?
  Does it have a 204 (no content) response code?
  In this case, something would have caused "manage_menu" to
  return a Python false value. ZPublisher turns such a value
  into a 204 response and almost all browser handle this response
  in the wrong way.

  If you do not see the "manage_menu" request, you may
  activate the "trace" logger (formerly called Big-M log).
  It logs 4 entries for each complete request.
  Missing entries indicate in which part of the pipeline
  the request got stuck.
