I'm experiencing a new issue with Contact Form 7. I'm using WordPress 2.9.2 and Contact Form 2.1.2 (which I reverted to 2.1.1 to try).
When submitting a form, (it's here http://www.greenunivers.com/contact/essai-deals/), the spinning arrow is loading, loading, it's endless, which makes the user think the mail isn't sent.
More strange now : the mail is somestimes sent, sometimes not. I'm not sure why, I haven't been able to identify why some are not sent. Perhaps I should have some error messages on the form that I don't get.
At this time I have Contact Form 7 2.1.1 because I wanted to try an older version, but the problem still exists with 2.2.2.
