Hi Stacy!
I ran into the same problem today and found a solution. Thought I’d would share it with you in case you’re still looking for a solution.
In your custom.css paste the following code:
input[type="checkbox"] {
-webkit-appearance: checkbox;
}
In the default css this reads “none” instead of “checkbox”, hence nothing is displayed in webkit browsers ??
Hope this helps,
Ruud Denis
