I agree with @David morgan! VERY helpful! I've been WANTING to do EXACTLY this, and this answer from @~Z~ Man... well... I wish I could get those kind of answer ALL the time! :)

Firstly, thank you for your time - It really is appreciated.

In regards to your solution, that has to be one of the clearest, most straight forward explanations ive received in a very, very long time.

Ive made the change, its worked, and I understand a bit more on how everything is structured.

Thanks you very much

Stay safe

Before doing any changes: Disable Ossn cache on your admin backend!

Look into components/OssnAds/ossn_com.php
and find the line ossn_add_hook('newsfeed', "sidebar:right", 'ossn_ads_sidebar', 300);
The last parameter (300) shows the place number in a chain of widgets which will be added to the sidebar

Now look into components/RssFeed/ossn_com.php
and find the nearly similar line ossn_add_hook('newsfeed', "sidebar:right", 'com_rss_widget');
This time there's no place number at all - which means it defaults to 200 - and that's why the feed gets displayed BEFORE the ads.

Thus, all you have to do is giving the feed's hook a larger place number than 300, and it will be hooked in AFTER the ads, so change that line to ossn_add_hook('newsfeed', "sidebar:right", 'com_rss_widget', 301); and you're done.
