# 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). {% hint style="warning" %} **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.
