I guess this must already be answered somewhere, but I cannot find it in the Forums or Documentation.
I set up a site-wide Related Posts list using WPSP, located in the Sidebar when individual posts are viewed. (Even for just a simple word list, WPSP is more useful than the standard Related Posts widget because I can select or exclude posts from the list by categories.)
However, when I select Date as the organising criterion, it seems to deliver them first in alphabetical order of categories, and then by date. So if a category beginning with ‘A’ has an old post, that always appears as the most recent post.
I’m sure this is not what you would intend, so please tell me what I have missed. (I have currently set it with no categories selected, so that all are delivered.)
Thank you and best wishes.
