We are experiencing issues when using the Gravity Forms reCATPCHA add-on. Forms will not submit while it is activated. Using the latest versions of Gravity Forms and the add-on.
If the page containing the form has a JavaScript issue, the reCAPTCHA response won’t be added to the submission, which can result in a general form validation error without any field-specific errors.
Caching and optimization plugins (e.g. Speed Optimizer, WP Rocket) and services (e.g. host provided, Cloudflare and their Rocket Loader feature) have been known to cause issues like this. We recommend excluding pages that include forms from those features.
See the following page of the documentation for more details:
The issue appears on a local environment (spun up with Local) using just Gravity forms, the add-on extension and the Twenty Twenty-Five theme.
In that case, the next most common reason is that the reCAPTCHA response failed validation. You can test with logging enabled to confirm if that is the cause:
Here’s what I get from the log:
25-04-01 16:46:30.489418 - DEBUG → Gravity_Forms\Gravity_Forms_RECAPTCHA\GF_RECAPTCHA::validate_submission(): Validating form (#5) submission.
2025-04-01 16:46:30.489479 - DEBUG → Gravity_Forms\Gravity_Forms_RECAPTCHA\GF_RECAPTCHA::initialize_api(): API Initialized.

That confirms something is preventing the reCAPTCHA script running on submission. Check the browser developer console for JS issues.
