Problem:
When copying and pasting the keys from reCaptcha mailhide into the configuration text boxes I ended up with a whitespace at the end of the private key. This led to the following obscure error:
warning: pack() [function.pack]: Type H: illegal hex digit in recaptcha\recaptchalib.php on line 237.

Suggestion:Trim whitespace from user key inputs before using them throughout the module.

I'm having the same problem but do not appear to have any whitespace at the end of the keys. I also looked at a similar (closed) issue that said "Using a different key in the Input Filter Section fixed it"...which I assume means getting a new key from recaptcha...am I reading that correctly?
