With the Protected Content plugin, then path is /register. When one clicks the button "Signup&q

Hi folks,

With the Protected Content plugin, then path is /register. When one clicks the button "Signup" it is still /register. My question is, "how does one adjust the design on the 2nd page after clicking "Signup"?

I can adjust the page design as wanted on /register of course. But, I am looking for where I need to adjust the design of the page after one clicks on "Signup"
