MEMBERSHIP PAGES – REGISTRATION FORM AND POPUP NOT SHOWING

I have turned of all plugins except for membership, and I cannot seem to get the registration popup to show, I am using the shortcode , [subscriptionform]. And I have enabled the “popup” in the membership>options panel..

the only thing that shows up is

“We have the following subscriptions available for our site. To join, simply click on the Sign Up button and then complete the registration details.”

though, there is no “sign up” button..

??

thank you
