It’s a bug.
To fix it edit classifieds-pictures.js and substitute every ‘j’ with ‘jQuery’.
line 94:
j.post( ajaxurl, {
change it to
jQuery.post( ajaxurl, {
line 74:
link = j(this).find('.edit-classified-picture');
to
link = jQuery(this).find('.edit-classified-picture');
line 78:
favorite_link.appendTo(j(this).find('dt:first'));
to
favorite_link.appendTo(jQuery(this).find('dt:first'));
It should work now.
