Content Security Policy (CSP) is a protocol that acts as a security measure for cross-site scripting.
For the CSP violation error, here are a few things you could try, to fix:
-Check if you have any plugins on the browser.
-Try clearing the cache of the browser you are using.
-Try logging in from a different browser.
We hope that doing these would fix the issue. If you are still seeing an error, write to support@chargebee.com
