If there are no visible errors but the affiliate signup form still does not function—despite all required data being filled in correctly—and clicking the Signup button does not trigger any response, a deeper investigation is necessary. Use your browser’s console to inspect the signup form; you may encounter the following error:
uncaught exception: com.google.gwt.event.shared.UmbrellaException: One or more exceptions caught, see full set in UmbrellaException#getCauses
This error typically occurs due to issues with your reCAPTCHA configuration. Please verify your reCAPTCHA settings under Configuration > Affiliate Signup. The issue is most likely caused by missing reCAPTCHA private and public keys.
