Why am I getting an error Bad HTTP response (302 Found)?

Q. Why am I getting an error Bad HTTP response (302 Found)?

A. The most common cause of this error is that the URL you entered redirects to another URL.

Please, check this by going to the URL you entered in ManageWP and check if the URL in the address bar of your browser changes. If it does, you need to remove this redirect.

The URL you enter when you try to add a site to ManageWP, needs to point to your WordPress homepage. Check the General Settings inside the admin area of your site and make sure that the Site URL matches the URL you entered inside the Add Site window.
