XFolder displays this message when you select the "[Configuration folder is empty]" item in a submenu. This menu item appears only when you have put a subfolder into XFolder's configuration folder which does not contain any valid objects.

Remedy:

Put WPS objects into the corresponding subfolder of XFolder's configuration folder. The corresponding subfolder carries the same name as the submenu you have opened.
