After update Cordova 5.0 in my system, I create new applications. When I tested my application on a device that time I get an error in the console log:

No Content-Security-Policy meta tag found.
Please add one when using the Cordova-plugin-whitelist plugin.: 23.

I add meta in the head section

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src: 'self' 'unsafe-inline' 'unsafe-eval'>

But again, I got the same error, in the application I use in-app browser plugin and 7 of other website links.
