I just upgrade my ojs 2.3.7 to the latest ojs 2.4.2
The problem is, I can't seem to get the reCaptcha feature to work.
Even the normal captcha did not work in the old version (2.3.7) although the font location was correct.
I have entered my public and private key in the config.inc.php, and removed the semicolon.
- Code: Select all
; Whether to use reCaptcha instead of default Captcha
recaptcha = on
; Public key for reCaptcha (see http://www.google.com/recaptcha)
recaptcha_public_key = <my public key>
; Private key for reCaptcha (see http://www.google.com/recaptcha)
recaptcha_private_key = <my private key>
but there's no reCaptcha validation on the registration page.
Any idea how to enable it?
