Membership 2 Signup page not working with Divi Builder

When you go to this page http://sharlaember.com/register/ and select to signup for the membership then page will lose the format from the Divi builder.

Tried to apply the solution here https://gist.github.com/panoslyrakis/a802a223b5ca52dcd707d733e5788b43 but got the same result. (Adding MU Plugin)

Thanks in adnvance.
