Ads not appearing on Search and Tag Pages (The rest are fine)

Hi, may I know why my ads are not showing on Search Pages and Tag/Archive Pages? I’ve checked on the boxes for these pages. The other pages work fine though. If you click on the provided link, you’ll see the blank space before post and separate space between widget. Those are my ads not showing up. The fact that they are showing on other category pages means it’s probably not the ad size problem? By the way, these are adsense ads. I tried amazon ad and it works fine at the bottom. Could you take a look for me? Thanks
