As you can see the color to click on join is in a white am not sure how to get it to show

I hope this is something simple to change and

Hi, Anthony.

The look of "Join now" button is styled by your template.
So you rather should ask template developers for advice.

But you may try to use:

.hero-area-wrapper btn {
background: #ffffff;
color: #555555;
border: 1px solid #555555;
}
