In the log messages of your feed you see the following warning:
"No items eligible for publishing were found."
Your feed contains a number of entries, but after applying your filtering options, RSSGraffiti found no stories eligible for publishing. This message appears for new or newly added feeds, when there are still no stories published from the feed.
The only thing that you need to do is review all your filtering options to make sure they are aligned with your actual needs.
Especially go to your feed edit form, and in the Filter tab pay attention to:
Cut-Off date/time: Make sure that it is set to the correct date time as not stories created before that Date and time will get published on your Wall.
Eligibility Age: A story will not be posted on your wall until it is at least as old as you specify here (counting from its publication date).
