I'm using Contact Form 7 on this new website :http://www.vizion-studio.com/contact/
When we try to send emails, the email is correctly sent, but I've got a error message like Error sending mail message. Please try again later or contact the administrator in another way (in french : "Erreur lors de l'envoi du message. Veuillez réessayer plus tard ou contacter l'administrateur d'une autre manière.")
I don't understand why...
Before the installation of this website on the URL http://www.vizion-studio.com, I've tested it here : http://www.bijoux-princesse.com/contact/ And the contact form did work perfectly... So I just don't understand what is different between those 2 websites ?
Could you help, please ?
