I have the plugin “Buddypress Members Only” and the redirect is just the full link to the registration page “http://www.websitename.com” and I have Buddypress Page settings set as Registration page the same link as previously mentioned – but when you try to access the locked page unless registered it removes the “www.” hence the constant registration loop
I found an issue, when the page redirects to the create an account section it removes “www.” and just has websitename.com – but when I add in http://www.websitename.com the registration works fine.
