FYI :: I had inserted code in my sidebar to show the number of posts publicly visible but In version 6.4.3 the field name in the table I called has changed. What was [evo_items__item.post_ptyp_ID] is now [evo_items__item.post_ityp_ID]
I suppose it is some conformity issue from post typ to item typ
Thanks @amoun. That's right, it's part of the new nomenclature, moving from blogs to collections or from posts to items.
