As far as I can tell, visiting the link as admin, reg-user, and guest, the page is functioning as it was designed by Jelsoft.
Could you please be more specific about what "does not work" about it? Is there another site you can show me where it DOES?
Perhaps what is confusing is the terminology. In Project Tools, a "report" refers to a set of search results that a user has saved. This differs from a bug report, which Project Tools refers to as an "issue". So what you are actually seeing on that page is "public reports", reports that any user can see, rather than one that you saved for your eyes only. Among these are "reports" that list all "issues" that were addressed in various versions.
