## **🧭 Overview**

If your WordPress contact form suddenly stopped working — especially after a site change, plugin update, or on a specific date — this guide walks you through the most common causes and fixes. If you have already tried troubleshooting before or reported this issue previously without resolution, skip to the **Escalate to Our Team** section at the bottom. Persistent or account-specific issues require hands-on investigation that goes beyond standard self-service steps.

## **⚠️ Before You Begin**

Keep these points in mind before attempting any fixes:

- If you have **already reported this issue** to support and it remains unresolved, do not repeat the same troubleshooting steps. Escalate directly using the instructions at the end of this article.
- Note the exact date the form stopped working. A specific break date (such as March 31) often points to a plugin update, hosting change, or server-side configuration change that occurred on or around that day.
- Back up your site before making any changes.

## **🔍 Common Causes of a Broken Contact Form**

WordPress contact forms most often break due to one of the following reasons:

- **A plugin conflict** — a recently updated or newly installed plugin is interfering with your form plugin.
- **A caching issue** — cached pages are serving outdated form markup or blocking nonce validation, which is a WordPress security token required for form submissions.
- **A hosting or server change** — PHP version updates, mail server configuration changes, or firewall rules can silently break form submissions.
- **An SSL or HTTPS mismatch** — forms submitting over HTTP on an HTTPS site will fail.
- **Email delivery failure** — the form itself may be working, but submission confirmation emails are being blocked or filtered as spam.

## **🛠️ Troubleshooting Steps**

Work through these steps in order. After each step, test your form by submitting a test entry.

1. **Check for recent plugin or theme updates.** Go to your WordPress dashboard and review your update history. If a plugin was updated around the date the form broke, try deactivating it temporarily to see if the form recovers.
2. **Clear all caches.** Clear your WordPress caching plugin cache, your browser cache, and if your site uses a CDN (such as Cloudflare or BunnyCDN), purge the CDN cache as well. Stale cache is one of the most common causes of form nonce errors.
3. **Test with all plugins deactivated.** Deactivate every plugin except your form plugin and retest. If the form works, reactivate plugins one at a time to identify the conflict.
4. **Switch to a default WordPress theme temporarily.** Theme code can interfere with form scripts. Switch to Twenty Twenty-Four or another default theme and test the form again.
