We were not using any Captcha at all. Today I did enable Cloudflare Turnstile but still same thing.
I can see few threads on User registrations not working in XF2.3, checking on SMTP settings, Localhost, server cache, etc
We are facing issue with user registration in our forum. After users enter all details on registration screen and click on the register button, screen refresh and lands back on same registration page.
Please let us where and what we can check to find the issue/error.
