Why can't Screencloud display other website?

Certain websites have security restrictions placed on them which limit where and how they can be shown. On the whole, this is a good thing. It means, for example, that your online banking is more secure. However, it also means that we can't display certain websites.

The only way around this is to talk to the administrator of the website, and ask them about loosening their security restrictions. Specifically, they'll need to change the ‘X-Frame-Options' header that gets delivered along with their website.
