I have a customer using OJS 220.127.116.11 and there is a lot of customizations where upgrading tot he latest version will take a fair amount of planning and time. I was just notified that reCaptcha v1 will stop working at the end of March.
Are there any steps or a list of files I need to update to get reCaptcha V2 updated? I found 3 files (recaptchalib.inc.php, notificationmailinglistform.inc.php and formvalidartorrecaptcha.inc.php) that i have updated to what appears to be the latest versions but it is not working.
If someone could throw out which files need to be replaced and where to get them that would be great.
