Does not work as it supposed to.Login in admin redirects all the time to Google, adding the captcha to wholesale form blocked sending the form without any other warning.

The Association have a network of 20+ sub-domains sites to offer individual access to sub groups, with another captcha in the formularies. Many of those sites will disappear in an upcoming revamp. I ran into Captcha4WP because the subscribe plugin of webling_ch, our database and accounting software chose it. We were exponentially spammed with fake registration. With Captcha v3 and a 0,6 sensitivity: no more problems.As we do not use captcha4WP in all the sites, support offered us a good deal that, as the webmaster, I could take without asking for a special budget. Thanks! Gilbert
