An interstitial displays its destination inside an iframe. A blank area usually means that no usable destination was selected or that the destination refuses to be embedded.
- In Simple mode, open Admin > Settings > Ads. Check that Interstitial Ad URL has a complete, working HTTPS URL.
- In Campaigns mode, open Admin > Campaigns > List. Check that an active interstitial campaign matches the country and traffic source of the visitor. The campaign must still have inventory and a working Website URL.
- Open the destination URL directly. Then check the browser console for mixed-content errors or responses that use
X-Frame-Optionsor Content Security Policyframe-ancestors.
AdLinkFly cannot override another website's iframe policy. Use a destination that permits embedding or ask the destination owner to adjust its policy. Do not weaken your own website security headers to fix a restriction sent by another website.
