Plugin Prevents BuddyPress Registration Form from Working

Hi there! I have a private members forum website that uses bbPress and BuddyPress. The site’s BuddyPress registration form stopped working and after deactivating and reactivating plugins one-by-one, I discovered that this plugin is preventing the form from working.

After filling in all of the form fields and clicking the “Complete Sign Up” button, nothing at all happens. I’d really like to use this reCaptcha plugin as an extra layer of security, but I don’t have much time to get this working and launched for my client’s very hard deadline. If you can help, I would very much appreciate it.

Thank you,
Melissa
