It appears you may have accidently un-approved the entries so they are now in the moderation queue. When in the moderation queue, they will not be displayed in the frontend.
On the Connections : manage admin page, add a checkmark to each entry at the left of every entry. Select Approve from the Bulk Actions and then Click Apply.
This will move them from the moderation queue back to the Approved entry list.
Lastly, disable the public_override option you enabled on the Connections : Settings admin page under the General tab.
Hope that helps!
