I have this issue, Before today Contact widget was working fine, suddenly it stop sending email, I got an error message saying "Mail not sent".. I started to fine solutions until I manage to avoid getting the error message by deactivation the HTML Newsletter template plugin...
But and issue persisted.. no email was sent... so after some re-settings I give up, and decided to uninstall the contact widget plugin.. the uninstalled and re installing..
after setting old values.. I manage to perform a successful email send click... but now the success message wont shop up..
is like widget (which I assume use asynchronous call) doesnt recives successful acknowledge... cause all fields remain filled..
so how should I proceed?
also I end up using this plug in when trying to achieve a successful email sent.. do you think now it is messing around
with this widget?

Any input is greatly appreciated...
