created two dummy courses, i understand at least 1 unit has

hi,
created two dummy courses,
i understand at least 1 unit has to be published for a course to show so i created and published it.
i made sure the start date was today that did not work.

i tried all sorts of settings but under http://www.site.com/courses it keeps showing "No Courses Found"

what am i missing ?

kind regards.
