I recently installed Codoforum for the first time. The installation was flawless, but when I turn on the option for reCaptcha and try registering a test account, I get this error:

{domain-sys-path}]/html/sys/Ext/recaptcha/recaptchalib.php on line 40

I'm at a loss of what would be causing this. Can someone help me troubleshoot?
