If you recently encountered an Error: Cookies Blocked or not supported by your browser. You must enable cookies to use WordPress. I can bet it’s must be frustrating.

Cookies Blocked Error on WordPress

Don’t worry, I will walk you through how to troubleshoot this error and login back to your website.

How to Fix A Cookies Blocked Error

I will show you a couple of methods to fix the cookies blocked error.

1 Set Cookies Domain

Okay, When you first see the error just refresh the browser and try to log in again. I had faced similar cookies error and sometimes, Page refresh fixes normally so, do this first just to make sure.

Next, you need to add the following code snippet is wp-config file.

// Set cookie domain for login cookies
define( 'COOKIE_DOMAIN', '.domain.com' ); // change domain.com with your actual domain

Make sure to add the code snippet above the line.
/* That’s all, stop editing! Happy blogging. */

If you are using a multisite and the above piece of code doesn’t work you can try this one.


2 Bypass Cookies

This is not an ideal solution it just kinda ignores the requirement for site cookies to login.

What you need to do is add the following code snippet to your theme’s functions.php file

setcookie(TEST_COOKIE, 'WP Cookie check', 0, COOKIEPATH, COOKIE_DOMAIN);


The Code Snippets plugin makes it very easy to not just add PHP snippets to your website but also manage all the snippets you add.

You can activate and deactivate certain snippets, and even adds notes about what they do. It even has better error handling to avoid the PHP error scenarios.

To install it, simply go to Plugins > Add New and search for Code Snippets.

The traditional or normal way to add PHP snippets to your theme is to add directly in your theme’s functions.php file.

However, make sure you are using a child theme otherwise you will lose all changes once you update your theme.

3 Other Troubleshoot Methods

Every Wordpress site is different and if for some reason none of the above methods worked for you, Try one of the following methods.

  1. Delete the .htaccess file from your server, just have a backup copy in case you need it later. If this fixes the error go to site settings and save the permalink settings without any change it will create a new .htaccess file.
  2. Disable all plugins with the help of FTP rename the plugins folder to anything, It will disable all of your plugins and hopefully also fixed the error. Rename the folder name back to original and enable plugin one by one. Normally Caching or security plugins cause this kind of problem.
  3. Remove //define('COOKIE_DOMAIN', 'www.domain.com'); in your wp-config.php. If such code exists in your wp-config.php
  4. If you recently installed SSL plugin make sure it redirects to HTTPS properly.
  5. It’s rarely caused by an issue in your theme. You can rename the active theme folder name to anything and it will revert back to default Wordpress such as 2019 and will fix the theme related problem. Delete and reinstall your theme if this was the cause.
