Website forwarding through DNS - new account needed?

Hi there,

I am running a platform called wecreate. The member area is hosted on my website www.tommyadvice.com/wecreate (through webflow). For the platform I have registered a new website: www.wecreate.today. I want to change the DNS of this website to the tommyadvice.com details, but just found out that memberstack doesn’t recognize the closed membership platform anymore, and everybody had access to the hidden pages through www.wecreate.today. Any idea how to solve this? Thx!
