ERROR: This page is using an unprefixed version of template {{Pp-template}}

Use {{Wp/na/Pp-template}} instead and replace all occurences of {{Pp-template}} in Wp/na/ prefixed pages by that.
You may like to check 9 templates in Category:Wp/na/Templates using unprefixed template Pp-template first to remove all occurences from those templates which will fix the pages containing those templates too.
