Hi David-
Thanks for the report, and thanks for using the Crio WordPress supertheme. You’re experiencing a bug with the starter design– basically the diagonal decorations are “on top” of your button so it’s not clickable.
We’re releasing an update for Crio soon with a fix for this bug, but you can fix it immediately with a little bit of Custom CSS. Navigate to Customize > CSS/JS Editor and paste this line into the CSS Code:
body:before, body:after { pointer-events: none; }
