How to Fix “Cookie Check Failure” or “Cookie Nonce Invalid”

Welcome to Eireview – Extractive Industries Review! In this article, we will address an issue that many WordPress users have been facing lately – the “Cookie check failure” or “Cookie nonce invalid” error. If you’ve encountered this problem, don’t worry, we’ve got you covered. Read on to find out how to fix it.

How Does This Issue Occur?

When using a plugin that performs asynchronous queries (ajax requests), cookies are used for authentication. These cookies ensure that the requests are made by you and not by someone with malicious intent. However, some caching plugins can cache these cookies, leading to an error when they are used after expiration or right before expiration.

Identifying the Cause

It has been observed that this issue has become more prevalent after a recent update of WP Rocket. If you are using WP Rocket and experiencing the error, then it is likely the cause. However, similar problems could arise from other plugins or systems like Comodo (Application Firewall) or mod_security set by your hosting services.

How to Fix It?

The good news is that fixing this issue is relatively simple. Here’s what you need to do:

  1. Disable the caching plugin temporarily while the problematic process is running. This will prevent the caching of the authentication cookies during that time.
  2. If you want to keep the caching plugin enabled, check the FAQ section of the plugin for guidance on how to resolve this specific error.
