Please help! My checkout button isn't visible. I can find it because it is there and when my mouse scrolls over it, the hand pops up, but nothing is there that says "check out". When I try to edit it, this is what I see - no options to add contrasting colors. I've tried to edit the code in the file theme.liquid, but it did not work. Please help. This should be an easy fix but this is so frustrating.
