@yakos…like I said using another plugin should not be necessary.
I have two sites both at WP 3.5.1 and both using Contact Form 7 v 3.3.3
both with same host provider but on different servers.
One works the other does not. Why? I checked into it some and the only thing I see different is the PHP version used on the server side are different version.
The server side newer version of the PHP v 5.3.21 is the site NOT working,
and the server with PHP 5.3.18 works.
