For me the non-www version of the website redirects to ads, and the www one redirects to the non-www one that redirects to ads. Freenom World is having problems lately, so changing the DNS to a faster one, but not Freenom World, should work fine. To fix the first issue, try removing your domain and re-adding it from the “Addon Domains” section of the Control Panel, and then move the WordPress files to the yourdomain/htdocs folder, where yourdomain can be replaced with your domain. To fix the second issue, you should change the DNS to other ones but not Freenom World.
It looks like the DNS records in our nameservers have gotten corrupted for your domain. Can you please try to remove the domain from your account and then add it again? That should fix the broken DNS records currently there.
