Ok but the problem still stands. If i put more than one shortcode all of them brings the same posts with the same order. I want to put more than one shortcode in the same post, different places, that brings me different posts in different orders.

Thanks for the reply, it worked, but not as intended.

I have the code inserted a few times in one post. I thought that each time i put the shortcode in the post it would get different posts and randomize them, but instead all the shortcodes comes back with the same articles and in the same order.

Is there a way to make each shortcode show a different set of posts in random order?

Forgot to mention that i'm using localhost so i cannot give you access to admin or give you site's address

I'm using "penci related post" shortcode inside posts to bring some "related posts" but the "random" order is not working:

[penci_related_posts dis_pview="no" dis_pdate="no" title="Artigos relacionados" background="" border="" thumbright="no" number="4" style="grid" align="none" withids="" displayby="cat" orderby="random"]

What i want is to show other posts from the same category of the post being read but in random order so the articles are not always listed the same.

I put this code multiple times and the order is always the same.

I already checked that i have lots of posts in that same category so it should show more combinations than the only one being showed.
