WordPress Are You Sure You Want to Do This
When you try to save a post, activate a plugin, or change a setting inside WordPress and you get a dead-end page that just says “Are you sure you want to do this?” — with no button to confirm — WordPress has blocked your action because a security check failed.
WordPress protects every admin action using something called a nonce (short for “number used once”). It’s a short-lived token that gets attached to forms and action links to prove the request is legitimate and came from you. When that token is expired, missing, or doesn’t match what WordPress expects on the server side, you hit this wall.
The reassuring part: this error almost never means your site is hacked or broken. It’s usually a caching issue, a URL mismatch, or a plugin stepping on the nonce system. Most fixes take under five minutes.
You should see: The action completes successfully without the error page appearing.
You should see: The error disappears, confirming the cache plugin needs reconfiguring to exclude admin URLs.
You should see: Both fields display the same URL, such as https://yourdomain.com, and nonce errors stop.
/* That's all, stop editing! */:
define( 'WP_HOME', 'https://yourdomain.com' );
define( 'WP_SITEURL', 'https://yourdomain.com' );
You should see: Admin access is restored and the nonce error no longer appears on those actions.
You should see: The action succeeds with everything off, then fails again only when the conflicting plugin is re-enabled.
You should see: A new .htaccess file in your root folder, and the error resolves if a corrupted file was the cause.

Almost certainly not. This error means WordPress’s built-in nonce verification couldn’t confirm the legitimacy of your own request — usually because a token expired in cache or a URL changed. It’s the security system working correctly, not evidence of an external attack.
Migrations commonly change the domain, protocol (http to https), or URL structure. Because nonces are generated using your site URL and validated against the active user’s session cookies, any URL mismatch introduced during the move will break nonce checks. Updating your WordPress Address and Site Address in Settings → General — or defining them in wp-config.php — is the fastest fix.
Yes. If you have front-end forms that use WordPress nonces — WooCommerce checkout pages, membership login forms, AJAX-powered contact forms — and those pages are being served from a full-page cache, visitors will hit the same expired-nonce problem. The fix is to configure your caching plugin to never cache those specific pages.
In the vast majority of cases, no. Clearing caches, correcting URL settings, and identifying a plugin conflict are all tasks any site owner can handle without writing code. You’d only need developer help for unusual situations like custom authentication setups, server-level caching configurations, or deeply nested plugin conflicts that require reading source code to untangle.
