Why isn't our Profile displaying on our Joomla webpage?
This has kind of been stated before, but you need to make sure that what you are exposing to Joomla is viewable by all unless you are requiring people to log in first before they can see the content (such as with a members area). You may want to elaborate on what your end goal is, because a profile search may require higher permissions than a profile view. If you are looking for just a general directory listing, you may not need a search.
