Payment Form doesn't seem to work with Invisible Recapcha. It appears JoomDonate does, so would great if all products did. Or offered the option to select which plugin to use, instead of just yes or no.
Payment Form does works with invisible recaptcha. Have you configured your site to use invisible recaptcha yet? If not, please configure and Payment Form will work well with it
Please note that when you use invisible recaptcha, the captcha badget will be hidden and you won't see it displayed (normally, it will be displayed at bottom right of the page). Maybe you don't see it, and that's why you said it does not work?
Multiple users were unable to submit payments - the attached error was shown. Not seeing the recaptcha badge on that page then made me believe that was the culprit. Disabled recaptcha allowed the payments to work.
I would like the badge be visible, or at least configure to show or not, to confirm it is working and installed correctly.
