Trouble with content security policy

Looks like you have 2 Content-Security-Policy issued. If multiple CSPs the strictest rules from both will apply (all sources/tokens should pass via both CSPs unscratched).

Content Security Policy could be delivered 2 ways:

  • via HTTP header Content-Security-Policy: (prefereed)
  • via meta-tag (restricted possibilities)

So you need to check for double <meta http-equiv="Content-Security-Policy" in the HTML code.

And check the HTTP response headers(because CMS could publush CSP by default) in the browser developers tool (Crtl+Shift+i in Chrome and Crtl+Shift+k in Fifrefox -> Network tab -> select main page at the left window and look Response headers):
response headers in the browser console
