Have you ever installed a new theme and found that there’s now a yellow background behind your ads? It happened to me and I kept thinking that something was wrong with my adsense code. Well it wasn’t…
All you need to do is open your CSS file in your theme and find #fff9c0 or #ff9 (likely where it mentions “ins”), then replace it with white or your background color. Full instructions provided on Botcrawl if you need more assistance.
