Contact Enhanced Form returns 401 error at "Send"

Since I removed ReCaptcha version 2 and implemented ReCaptcha version 3 (Invisible ReCaptcha), visitors using the Contact Form receive this error message after clicking the "Send" button:

0 Empty solution not allowed.

Contact Enhanced Pro is properly configured to use Invisible ReCaptcha and the Contact Enhanced Pro plugin is active. Joomla plugin for Invisible ReCaptcha is properly configured with the correct Site and Secret keys. User logins (Community Builder) work properly with Invisible ReCaptcha.

My Joomla website ( www.acmetreadway.net/ ) uses the current version of Joomla (3.9.1), PHP (7.2), and MySQL.

I appreciate any suggestions you may have. I've also posted a support query with the Google ReCaptcha forum.

Cheers,

Dear Don,

I have just tested our form locally with ReCaptcha V2 and Invisible ReCaptcha and Contact Enhanced worked both times.

I've checked your form and it doesn't seem to have ReCaptcha Enabled. Can you please either enable it for Contact Enhanced or create a temporary contact and enable it just for this temp contact in the Contact Options? Then provide a direct link, so I can take a closer look?

Best regards,

Douglas,

I have this problem with several Joomla 3.9.1 sites, and I checked the configuration on each to ensure that the settings were proper. Still had the problem, so i reconfigured Contact Enhanced Pro to disregard Invisible ReCaptcha and rely now on the Honeypot feature solely. The forms now work, and that's what counts.

Cheers.

Dear Don,

Ok. Let me know if you'd like to me to continue to investigate this issue in the future.

Best regards,
