Captcha not working

[Big_J]

I have noticed no new registrations on my site the last week, I upgraded to the latest version about a week ago. I tried registering a test account and the captcha / image verification does not show any characters, just a blank box with the background colors but no numbers/letters

What do I need to do to fix this?

Thanks

Did you enter the reCAPTCHA™ Public Key and reCAPTCHA™ Private Key?

I am using the image verification that comes with vb

Which one?

1.) Image Verification or 2.) reCAPTCHA™

GD must be compiled with FreeType 2 support. You may want to ask your host about this. However, IMO reCAPTCHA works more effectively.
