reCAPTCHA script is still loading. Wait a moment and try again
Captcha gate shows captchaGate.recaptchaLoading when submit/continue is attempted before the reCAPTCHA script finishes loading.
Why this happens
Slow network, blockers delaying gstatic/Google scripts, or a very fast click after page open. Distinct from Could not run reCAPTCHA. Try again (execute failed after load).
Diagnose and fix
1. Wait a few seconds until the widget appears; retry.
2. Allow Google captcha scripts; disable aggressive blockers for this site.
3. Refresh if it never loads (Could not load captcha).
4. Admin: confirm keys if load never completes (reCAPTCHA is not configured).
