yes you are right but the problem i don’t want to create new feed page for that wordpress having default functionality to spread over blog post from reading option and we can access it from url like https://www.websitename.com/feed it’s default functionality. but i can access this particular url without admin login and also i can’t exclude feed url because it is not a page it is created by wordpress.
so what the other way to we skip this https://www.websitename.com/feed url for login checking or bypass from maintenance. if you can help me to doing from customization from codding side then also is in my fever.
