I have our WordPress multisite https://website.com setup on SiteGround server. I now created a new page https://website.com/test and want to show it as https://newpage.com. I created an A Record in CloudFlare where newpage.com points to our SiteGround server ip and is piped through https. I am trying to do the mapping but receive the following error.
What needs to be done to make this work? Thank you in advance!
