Cloudflare is a global network of servers and other technologies that helps protect websites from cyber threats. It provides encrypted connections, DDoS protection, and privacy features to help keep your online experience safe and secure. The provided HTML code indicates that the website uses Cloudflare's security service to prevent unauthorized access. When you attempt to access klaviyo.com, which appears to be a marketing automation platform, it triggers the security solution used by Cloudflare. As a result, you are unable to access the site due to a blockage. To resolve this issue, you will need to enable cookies on your browser. This can be done by following the instructions provided in the code: ```javascript if (!navigator.cookieEnabled) { window.addEventListener('DOMContentLoaded', function () { var cookieEl = document.getElementById('cookie-alert'); cookieEl.style.display = 'block'; }); } ``` This code checks if cookies are enabled in your browser. If they are not, it adds an event listener that displays a cookie alert when the page loads. By enabling cookies, you should be able to access klaviyo.com again.
