Hi VividCortex,

I noticed that the solution of romelgomez works. However the message: "captcha verification expired" is also removed. It just loads a new recaptcha widget.

Yes, that's what happens, exactly as described by @wniehof. When the captcha expire, a new captcha is loaded, you never see the 'captcha verification expired', in this point we can say that is just a patch.
