Hi, on my site, the subscribe to newsletter function has been working fine for a very long time. The Acymailing captcha is set to "Invisible reCaptcha" (although I now as well see "CAPTCHA - Invisible reCAPTCHA") and all the Keys are there.
Just to stress: it's been working fine for months and months.
Now all of a sudden the subscribe forms will not work, just produce the "The captcha is invalid, please try again" message, in all the different browsers that I tested.
How do I solve this? Thanks!
