Hi,
Before I tried WordPress default function I already tried PageNavi.
It does the same thing, it shows, just like it does now, only with some styling (PageNavi’s default style). When I click the pagination (doesn’t matter which page) it always shows the same content.
Now I also searched this through on Google. Guess it has something to do with query_posts()
but I can’t figure out what it is.
I used the link below to add it to my theme.
