All 208 items disappear at random times on the public site. Sometimes after 24 hours, sometimes after 48 hours; but it eventually happens.
The only thing that will make them visible is to log in to the admin page.
Then all items return to the public site.
Are all of your items checked public?
If some are public and some are not, you will only see the items that have been checked public on the public side of the website. If you log into the administrative interface, you will see all of the items--public and not public--on the public pages.
