I´ve a big problem with SPAM registrations in my site.
I´m using Wordpress 4.9.1, Classipress 3.6.1 and Citrus Night 3.0 as a child theme.
Google reCAPTCHA is apparently working, but in recpatcha control panel i see this warning:
Captura de pantalla 2018-01-04 a la(s) 04.01.55 p.m..jpg
Please, can you tell me how to resolve it? It coul be the solution to the SPAM registration problem?
Thanks in advance for your help.
