I have a few people who have tried to register on my site but the recaptcha is giving an "invalid" error and so they cannot complete. I tried to reset and re-input the codes from Google and it still gives the error. I have, for the moment removed the captcha, but I know how many fake ones I got before I put it on.
Is there something I can do to fix this?
- Please make sure you don't have other reCAPTCHA plugins installed, you should use the built-in reCAPTCHA in Forums > Tools > Antispam Tab.
- Make sure you've generated and inserted API keys for v2 "I'm Not Robot" version of reCAPTCHA
- Make sure your forum pages are not cached. If you have any cache plugin, you should exclude forum page from that plugin, here is the instruction: https://wpforo.com/community/faq/wpforo-and-cache-plugins/
