I installed the membership plugin on a site which

I installed the membership plugin on a site which is running the H.E.L.P Theme, which is using a drag and drop pagebuilder.

When I create a Register page the register a subscription (I have a free level thats all) the page form doesn't show a Sign Up button. I inserted a signup button to the page (see attached screen dump). When I click the singup button a popup signup form should appear but the page is blank without any signup form (see attached screendump).

What are my options? Should I create a link to a signup page (standard) and then assign site users to automatically get the free level?
