Login Conflict with Formidable Forms

We use Profile Builder for the private site portion and have for years. With the last update, we can no longer login using our Formidable Form, only the Profile Builder form when in private mode. It was working fine before. We don’t use the Profile Builder one because it’s not as easy to style as Formidable and we use very complex forms throughout the site. We really need the private site feature. Can you recommend anyway for us to allow private site again without having to use the Profile Builder login form like it’s been for years?
