Validation Error Message won't hide when valid

Question

UPDATE 2: I figured out that the title of the input was for some reason being displayed as an error message, I used ignoreTitle: tru

Answer 1

just comment the errorplacement option and it will work as required.

$(".guestlist-form").validate({
     ignoreTitle: true,
     errorClass: "error-class",
     validClass: "valid-class",  

     rules: {
        emailaddress: {
            required: true,
            email: "Please enter your correct email address."
        }
    },
    /*errorPlacement: function(error, element) {
        $(".myerror").html('');  // clears previous error messages
        error.appendTo( ".myerror");
    },*/



    messages: {
                 emailaddress: {
                 required: "Please enter your full email address."          
                }

    }

});
