AeonFree is providing a very good service of free hosting but just like other free hostings, the issue is always the same. I signed up for free hosting with a subdomain but no matter what changes I made in the FTP file manager for index.html of my free subdomain site, nothing made any effect on the website. I tried installing WordPress and other CMS a couple of times through softaculous and they installed but there was no effect on the site.
My guess as everything points to this issue after thorough research is that nameservers of subdomains are not pointing correctly to the free hostings. Please solve this problem, this is the obstacle that stands in your way to becoming the best free hosting provider.
