Sign up page not active on protected content plugin

Hello, i am done configuring protected -Content and so far its stable and
very easy to implement , compared to membership. However i notice that
after setting everything up, the sign up form does not proceed with
registering subscribers but stays back on the registration page, is this
peculiar to me or what is it?

i tried configuring the different payment methods but ultimately i will
be using paypal - single for finite subscription.

I have tried different browsers but no luck, any help of the reason why?

how do i replace the regular wordpress sign up widget with that of protected content?

Thanks
