Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self' https://recaptcha.net/recaptcha/ https://www.google.com/recaptcha/ https://www.gstatic.com/recaptcha/ https://www.google-analytics.com 'sha256-025gvQ+eqBBa1gPv3yDQ8ZOLbqIHFQ5jopH6xos0wKQ=' 'sha256-2RXRWvJ8W1J7QrR4EX63UeFGJeUbIZ9UU1+dFz0IAQM=' 'sha256-QZmDcSOrrfzgLM8OxOzmxtBDZfZeWBvkrF4be8MS1yE=' 'sha256-O0tVjDXXoPPdFk/hoQliTn3jTRfbaxW4cqCpGUluqjY=' 'nonce-/lbezDFZ9KZJMh3hH31wSA==' 'nonce-mLzifaDsq53Ee+JBT8SyiQ==' 'nonce-x547uxJjyfsmQDGUgD8K3Q=='". Either the 'unsafe-inline' keyword, a hash ('sha256-uAl5d/PUjfslEVIOj+a8ngY1SVHneHoEtaj8UPjP3rQ='), or a nonce ('nonce-...') is required to enable inline execution.
