How and where to change the number of ads in the "recent ads" block?

Displays 10 ads by default.

I change in the file:
\ oc-content \ themes \ beta \ functions.php

// RANDOM LATEST ITEMS ON HOME PAGE
function bet_random_items ($ numItems = 10,

10 by 8, no result.

Along the way:
MY DOMAIN.COM / oc-admin / index.php? Page = settings
The last ads for showing "set 8" in the frontend are further 10 ... I cleaned the cache ...

As I understand it, somewhere in the script you need to change, and which script, where is it located?

Ocsdmin - general - latest ads

I wrote that in the admin panel in the general settings I set the number of recent ads to 8, it is displayed further than 10 in the frontend! ...

As visible on following code, number of listings is taken from oc-admin > settings > general (latest items on home page)
  $max_items = osc_get_preference('maxLatestItems@home', 'osclass');

  if($max_items == '' or $max_items == 0) {
    $max_items = 24;
  }

  $numItems = $max_items;
