If you're having trouble seeing content using the Website App, we've released SSL secure hosting for any website you're hosting under our paid plan, so that all you should need to do is paste in your web address on the Website app.

If you're using the website app to be fully visible in all browsers, you'll want to have your content securely (also called https, or ssl) hosted -- this option is available on most companies that provide hosting. SSL means secure socket layer, and is the standard method of authenticating and ensuring content pulled from an outside source is safe and not malicious. 

To make your website visible using your own hosting company, such as Wordpress go here. Or to securely host your website yourself, using Bluehost go here.
