 * When sending contact form from my blog user gets this error message:
 * “Invalid HTTP_REFERER domain. The domain name posted from does not match the 
   allowed domain names from the form edit Security tab”
 * I don’t have a xclue as to whats wrong. Can someone help? Please respond as if
   to a six year old as I am not a PHP or Internet guru.

 * I have read replys to similar posts on this site. They say to uncheck this setting:“
   Enable Form Post security by requiring domain name match for …” I have looked
   at ever tab in the FS Contact form settings and see no check box that says “Enable
   Form Post security by requiring domain name match for …”. So I am still clueless.

 * [@mbrsolution](https://wordpress.org/support/users/mbrsolution/): I checked the
   link you suggested. It was the same solution I already read. They say to uncheck
   this setting: “Enable Form Post security by requiring domain name match for …”
   I have looked at every tab in the FS Contact form settings and see no check box
   that says “Enable Form Post security by requiring domain name match for …”. So
   again I am still clueless.

 * This setting under “Basic Settings” in the FS Contact Form settings seems to 
   correct the problem:
 * Return-path address (recommended):
    Set this to a real email address on the SAME
   domain as your web site. For best results, the “Email To” and the “Return-path
   address” should be separate email addresses on the SAME DOMAIN as your web site.
   help
 *  Enable when web host requires “Mail From” strictly tied to site. (recommended,
   see FAQ) help
