At the bottom of the code, line 639
$('#form-submit').prop('disabled', false).attr("onclick", "window.location.href='#';");
Once # is replaced with any URL this error appears:
Uncaught ReferenceError: validatetTextarea is not defined
line 626 code:
else if (!validatetTextarea()) {

The problem is, when the contact form button is clicked, a blank page appears with the text ‘Something Went Wrong’. If # is replaced with google.com or any link, it still display the same error.
