natjak608 on "[Plugin: Contact Form 7] Not sending anything but answers that "Message sent""

Hi,

I have used Contact Form 7 in another site and it's working well. Now I can't get anything on through, but form says Message sent... I'm using Pytheas theme, and yes it is behind password, but it's demo page they have example where Contact Form 7 is in use, so I think it can't be that.
