# reCaptcha Troubleshooting – Fix “Not Loading” & Verification Errors
When using **Super Forms** on WordPress, you may occasionally encounter issues where the Google reCaptcha element:
* Doesn’t display on the page
* Returns the error **“Google reCAPTCHA verification failed!”**
* Malfunctions when you have **multiple forms** per page
This guide walks you through all the major causes and step-by-step fixes.
### 1. Verify & Regenerate Your API Keys
Many reCaptcha errors stem from invalid or misconfigured API keys.
1. **Locate Your Keys**
* In WordPress admin, go to **Super Forms → Settings** and search for **“captcha”**, *or*
* go to **Super Forms → Settings** **→ Form Settings** and scroll to reCaptcha API settings
2. **Regenerate Keys**
* Visit the [Google reCaptcha admin console](https://www.google.com/recaptcha/admin).
* Delete the existing key pair for your site.
* Create a **new** v2 (Checkbox) or v3 key, ensuring you enter your site’s exact domain(s) under **Allowed domains**.
3. **Update in Super Forms**
* Copy the **Site Key** and **Secret Key** into Super Forms’ settings fields.
* **Save** and **clear** any caches (see § 4).

**Note:** If you switch from v3 to v2, you must generate a fresh v2 key pair—v2 and v3 keys are not interchangeable.
{% endhint %}
### 2. Check Domain & SSL Configuration
Google will refuse to load reCaptcha if the domain or SSL settings don’t match.
* **Domain Whitelist:**
* In the reCaptcha console, ensure **exact** match of your site’s URL (e.g. `example.com` vs. `www.example.com`).
* Add both variants if necessary.
* **HTTPS Requirement:**
* reCaptcha requires a valid SSL certificate on your domain.
* Mixed-content (HTTP scripts on HTTPS page) will be blocked by modern browsers.
### 3. Resolve JavaScript & Plugin Conflicts
reCaptcha injects its own JS; conflicts can prevent the widget from rendering.
1. **Console Errors:**
* Open your browser’s Developer Tools → **Console**.
* Look for errors like `grecaptcha is not defined` or `Blocked script`.
2. **Defer / Async Optimization Plugins:**
* If you use WP Rocket, Autoptimize, or similar, *exclude* `https://www.google.com/recaptcha/` from defer/minify lists.
* Or disable JS optimization temporarily to confirm.
3. **Theme Hooks:**
* Ensure your theme calls `` in the `` and `` before ``.
* Missing these hooks prevents plugin scripts from loading.
### 4. Caching & CDN Considerations
Caching layers may serve old JavaScript or block dynamic tokens.
* **Page Caching:**
* Exclude pages with active forms from full-page caches (e.g. via WP Rocket “Never Cache URL”).
* Or add query-strings to force fresh loads.
* **CDN Rules:**
* If you use Cloudflare, create a **Page Rule** to *Disable Performance* on your form pages so Cloudflare doesn’t strip query parameters from reCaptcha scripts.
