Hello, im new here, and i been following the tutorials to set up a page, and so far everything works fine.
I already have my page working on the host, with a custom domain, ssl certificate and redirecting to https with htaccess method.
But the problem is SmartScreen is blocking the page when it adds the /?i=1 suffix
You should definitely report this to Microsoft as being a false positive. Because the ?i=1 being harmful is complete nonsense.
Using Cloudflare avoids this suffix. But it would help a lot if you could submit a report to Microsoft about this as well, because it will likely help others too.
