Problems with membership plugin

Hi

Sorry, had to open a new ticket because no one is responding on the last thread.
I have an issue to get the sign up form visible on the website. If you click on one of the products on the homepage it will take you to the signup...from there it takes you to registration where all the text gets bunched up with the short code placed in and no sign up form appears? Any ideas?
