When i list posts of specified user, the pagination number links works incorrectly. The numbers of links inversed. The problem occur after when i change the ordering mode.

• To reproduce, just log in, click see users posts on a user profile.
• Change the ordering mode ascending or descending
• Then click on page numbers
• See the number links work incorrectly

ie.: https://terszobraszat.hu/forum/search.php?st=0&sk=t&sd=a&sr=posts&author_id=52

The error occured on prosilver and simplicity theme.

In my lang:

created time - elküldés időpontja
ascending - növekvő
descending - csökkenő

I debug it and follow the variables. 

When i comment out phpbb/search/base.php line 83:

// $start = $result_count - $start - $per_page;

Then all things work fine. The line 83 reversed the ids order but not needed.

I think maybe recache ids when the order changes is a good way too.

I tested two domain and on localhost to.
