We all know WordPress team has been trying their best to provide our blogs high-quality secured interface and they have been updating WordPress core time to time. After the release of WordPress 4.3 recently, most of the WordPress users started complaining about an error which occurred in their WordPress sites when they try to login to their sites from an anonymous browser or other computer.

For your information, the error is not specifically for WordPress 4.3 users but it can occur in other WordPress installations too and this method of solving the error is applicable on all WordPress versions.

So, in this article I’m about to guide in 2 different ways to solve:

“Error: cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.“

ERROR: Cookies are blocked (WordPress Error)

Method #1: Change wp-login.php to wp-admin without refreshing

• First of all, try to login to your site and see what happens.
• If you keep facing the following error, then please check your login URL.

• You might find your website login URL above in the browser like: yoursite.com/wp-login.php
• Here, go to yoursite.com/wp-admin without refreshing the page
• That’s it. If you no longer facing the error you are done or if you still troubleshoot that error please following the method #2.

Method #2: How to enable cookies for specific site in Chrome and Firefox
