I think it's an issue a plugin for mapping domains with one site on my multisite

The site is showing http://http:// automatically. I'm not sure where that's coming from. When I click on certain links it shows both so so the site doesn't actually com up.

The site is http://hearpreneur.com. If you click on the links on the home page (blog posts) it goes to http://http://BLOG LINK] or the secure version which is https://http://BLOGLINK.

Please advise.
