title: Refused to load the stylesheet because it violates the following Content Security Policy directive: "style-src 'self' 'unsafe-inline'"
body: <p>I m trying to load an external popup form created with a third-party tool. 
  I keep getting this error about CSP violations. Thing is I can load them correctly locally and they are only blocked when I deploy them on my provider's server. I dont know where these policies are coming from since I havent defined anything in .htaccess file (PHP web app with codeigniter)
  I checked all the relevant answers but nothing worked for me. </p>
