I tried to insert Adsense code after my post but above the related posts plugin and I could not do it.
I tried to enter the code in several php files but all of time my adsense appears after related post block.
I hope you are well today and thank you for your question.
To help you first i want to know how you are displaying the related posts on your site and please also share me the page URL from your site where it’s displaying.
