Using the built in reCaptcha in the latest version of Q2A, I can't get it to work. I have tried with my site set to secure and non-secure to check if it was a security issue. It does not appear to be. The keys go in fine (have tried v2, v3 and all variants of v2 as well) and every time someone tries to register it comes up with "Please complete the anti-spam verification".
There are others who have asked this question but with no solutions. I am running Apache, latest PHP on a Windows Server VPS backend.
I have tried different hosting platforms as well and nothing is working. I am so frustrated but more than happy to try any suggestions. Thanks in advance.
