Hi @FRESHPRNCE. Thanks for being part of GoDaddy Community! The AdSense option we have in Website Builder/GoCentral is only available in the US. My guess would be that the browser on one of your computers is cached to be on the US version of our site and the other is cached to a different region. You can change the region of the website your on by using the drop-down list in the upper left corner of our home page.
As for ads not displaying, whether or not ads display on a page that has the AdSense code is entirely up to Google. They dynamically choose content based on what's on that page. Sometimes they choose not to advertise on a given page. I hope that helps explain the situation.
