This is a very strange case which I don't know how to solve or even know
what's going on.
I have 8.636 posts (post type 'document'). 245 of them are published with
the same date (January 6th 2008).
When I filter by date: January 2008, I get all 245 (according the number
showed next to the pagination buttons) but the thing is I don't and plus I
get repeated posts! why?!
Funny thing is that when I change the "number of elements per page" to 50
(instead of 20) I get the proper list.. no repeated elements, etc.
Has anyone experienced this? It's super weird.
