No Ads Appearing on My Website

I recently started a blog and I’m putting adsense on my website. I purchased the pro version but nothing is appearing for ads on my website: https://www.bizprofitadvice.com. I pasted into the plug-in my adsense code but nothing happens. I’ve waited a couple days now and I don’t understand why nothing will populate? All I see are the red boxes on the site with no ads!
