If your application was disapproved because we cannot find the verification code in the root directory of your site, please make sure you are the owner of the website and add the code to the root directory. E.g. if “abc.XXXXX.com” is the root page of your site, you need to add the verification file to the root directory of “abc.XXXXX.com”

Anyone know how to fix this error? I appreciate the help from our WA member.
