After upgrading core to 5.7.1 we see “ERROR : Incorrect ReCaptcha, please try again.” on both the registration and login page in cases where the recaptcha has not been checked. Please make sure you have the correct plugin form (there are several for recaptcha) and check that there is not a conflict with another (possibly also recently updated?) plugin.
Thanks for your reply. I will investigate but the Login and Forgot password pages work as usual with your plugin.
Check to see if any other active plugins/themes are implementing a custom registration page. Good luck!
I’m sorry to bother you but when I try to deactivate your plugin the reCAPTCHA disappears from all forms. So I think I haven’t any other plugins/theme interfering with the Registration form. Am I wrong?
Disappearing from login, forgot password, and registration forms is correct behaviour when deactivating. Another theme or plugin may still be interfering when it is active.
