Re : Trackers for admin eyes only... how and why ?
It is just an assumption. I suppose that when you are not an admin, as only some infos are displayed, some html tags are missing because a {if} is not well formed in the template perhaps... (I suppose you configure correctly hidden field and public field in tha option admin, did you?)
An idea is to display your page as non admin , then goes on
http://validator.w3.org/ and gives the url of your page. Perhaps you will discover something strange.
Otherwise do you have an url that can be seen?
