I have inherited an OJS v.184.108.40.206 server and I see that this version of OJS will only support v1 of reCaptcha but not v2 of reCaptcha but reCaptcha is no longer available from google.
I want to enable captcha/recaptcha but the business do not want to upgrade from this version so I assume that captcha is now the only available option.
I have enabled captcha but when I go to register, the captcha image is black with coloured dots on it and no letters. Has anyone seen this issue and know how to resolve it?
The server is lamp rhel6, apache 2.2, mysql 5.1 php 5.3.3.
