Not showing success message but receive email.

See Why isn’t My AJAX Contact Form Working Correctly?

Thanks I have seen this page but don’t know how to check these points – sorry ??

This is most likely due to a Javascript conflict with either your current WordPress theme or one of the other plugins you are using – see Contact Form 7 Email Issues – there is a link there that covers Javascript Conflicts.

got the same problem..
I can click 10 times in a row on “Send”, but nothing happens.
I get the 10 mails, but no fail/success messages..

No plugins are active (except CF7)
