Websites use several different Website coding languages to work. All websites use HTML, CSS, and JavaScript to render the webpage to the visitor.
When the website is loading but the website is not displaying correctly, this is usually due to a coding error on the site. Usually, this is caused by JavaScript or CSS errors. This documentation will focus on diagnosing JavaScript coding errors using the browser console window.
If any section on the Checkout is not working properly, you can diagnose them by using your browser's Error Console. Each browser has a built-in Error Console for diagnosing scripting errors on your site.
Below will show you how to check the Error Console in Firefox, Internet Explorer, Chrome, Edge, Safari, and Opera.
