we use Google Ad Manager to manage all the banners on our website. It used to be working on two domains: www.enfsolar.com, and www.enfrecycling.com, but it stopped working on www.enfrecycling.com a few months ago. Anyone knows how to fix it?
Eg. this two pages have the exact same code, enfsolar.com can display the banner normally but the other one doesn't: https://www.enfsolar.com/about?dev=1 https://www.enfrecycling.com/?dev=1
Settings for the two domains is exactly the same, but it still doesn't work.
