Hi,
I' using contact-form-7 on one of my site and everything works just fine.
I tried installing it to another blog and the form won't validate (ajax?).
Here's the link to the form.
http://www.autoactualites.com/nous-contacter/
I tried with and without captcha. I uninstalled reinstalled and then recreate the page. I even created a new form... etc.
Thanks for your help.
