Fixing the Are You Sure You Want to Do This? Error in WordPress

Of all the WordPress errors, “Are you sure you want to do this? Please try again” is arguably the most confusing. It usually happens when you are trying to publish a post, upload a theme, or modify a plugin, and it completely halts your progress.

What Causes This Error?

This error is almost always triggered by a failure in Nonce verification.

A Nonce (Number used ONCE) is a security feature WordPress uses to protect URLs and forms from malicious hacking attempts. If a nonce cannot be verified—often due to a poorly coded theme or plugin, or hitting server upload limits—WordPress throws this error.

How to Fix It

1. Increase Upload and Post Limits

The most common scenario for this error is trying to upload a theme or plugin file that exceeds your server’s upload size limits, or saving a post that exceeds post variable limits.

The Fix:
You can increase these limits by creating or modifying a php.ini file in your root directory with the following values:

upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300
max_input_vars = 3000

If you don’t have access to php.ini, you can try adding these to your .htaccess file:

php_value upload_max_filesize 64M
php_value post_max_size 64M
php_value max_execution_time 300
php_value max_input_vars 3000

2. Isolate the Faulty Plugin

If increasing the limits doesn’t work, a poorly coded plugin is likely failing its nonce verification.

The Fix:

  1. Go to your Plugins page and deactivate all plugins.
  2. Try performing the action that triggered the error again.
  3. If it works, activate your plugins one by one, repeating the action each time, until the error returns. This will identify the faulty plugin.
  4. Once identified, contact the plugin developer for a fix or find an alternative.

3. Check Your Theme

If plugins aren’t the issue, your theme might be. This is common with heavily customized or outdated themes.

The Fix:

  1. Go to Appearance > Themes.
  2. Activate a default WordPress theme (like Twenty Twenty-Four).
  3. Check if the error persists. If it’s gone, the issue is within your theme’s code (usually in the functions.php file).
