Hi,

Contact Forms 7 are now stated having a input field using "name" is listed as a unavailable name or reserved word in Wordpress(see gkrellShoot_10-03-2017_103540.jpg). Refer https://contactform7.com/configuration-errors/unavailable-names/ and https://contactform7.com/faq/are-there-any-reserved-or-unavailable-words-for-the-name-of-an-input-field/

TheGem Theme uses "name" as a class to apply a content icon to the Name field in a Contact form(see gkrellShoot_10-03-2017_103854.jpg). This has the potential to conflict with reserved word.

As a work-around add this CSS to your contact page;

.wpcf7-form  .your-name:after{
  position: absolute;
  font-family: thegem-icons;
  right: 12px;
  top: 12px;
  font-size: 24px;
  content: '\e63b';
  color: #b6c6c9;
}

Where the class "name" has been renamed to "your-name", matching the input field for the Contact Form(see gkrellShoot_10-03-2017_104942.jpg).
