I've added more nodes and now there aren't any empty cell anymore but only 3 thumbnails are displayed and there should be 6 or 9...
what's wrong ?

IN fact the empty cells depend on the total number of nodes on the website. Amazing :-/

The problem solved itself, I don't know how but now it's working. Strange...
