Content Security Policy (CSP) refers to an extra layer of security to prevent attacks such as Cross Site Scripting (XSS).
To correctly display content coming from Blue Billywig, you might need to reconfigure your server to return the correct
Content-Security-Policy HTTP response header.
The following example adds your Blue Billywig publication as a trusted subdomain when content is embedded in an iframe (indentations and hard returns are added to increase readability):
content-security-policy: style-src 'self' 'unsafe-inline'; frame-src MYPUBLICATION.bbvms.com; default-src 'self';
