Pro site mess up firstpage when I add a link to Pro Site

Hello,

Have some issues with Pro Site.

1. Pro Site issue 1
The design got messed up when I add a link to http://egenhemsida.net/pro-site/ on our first page https://egenhemsida.net.

In other words: If I go in and edit our first page (WP Page Startpage) and if I add a link to our Pro Site signup page the design of the site breaks and the Pro Site plugin is shown on first Page over all content.

2. Pro Site issue 2
When a customer sign up to choosen plan they have to add credit card to activate the site. The problem is that if they close the browser or open our site in another browser their site can not be activated and they can not login and add their card.

Best Regards

Viktor
