When I go into the backoffice and try to access a template, it never comes up. When I view the console, I see an error like this:

Refused to display 'https://www.sctflash.com/umbraco/settings/Views/EditView.aspx?treeType=templates&templateID=5082' in a frame because an ancestor violates the following Content Security Policy directive: "frame-ancestors 'none'".

This only happens on production, not on my stage server or localhost.

I deleted the app_data folder to see if it would fix it but it did not.

I noticed when I look edit the template on my production site, it is like this, the response headers are these:

Access-Control-Allow-Headers:Content-Type Access-Control-Allow-Methods:GET,PUT,POST,DELETE,OPTIONS Access-Control-Allow-Origin:* Cache-Control:no-cache Content-Length:41216 Content-Security-Policy:frame-ancestors 'none' Content-Type:text/html; charset=utf-8 Date:Wed, 24 Aug 2016 15:17:44 GMT Expires:-1 Pragma:no-cache Strict-Transport-Security:max-age=15552001; includeSubDomains; preload X-Frame-Options:DENY

but on stage it is:

Access-Control-Allow-Headers:Content-Type Access-Control-Allow-Methods:GET,PUT,POST,DELETE,OPTIONS Access-Control-Allow-Origin:* Cache-Control:no-cache Content-Length:42090 Content-Type:text/html; charset=utf-8 Date:Wed, 24 Aug 2016 15:31:22 GMT Expires:-1 Pragma:no-cache
