Well, is your layer actually an adjustment layer? Second, change the reference color in the plug-in to white.
It is not an adjustment layer. I used command+Y (if that is the answer you were looking for).
I'm not quite sure what you mean by change the reference color, if you mean the option labeled "Color" that does not work. Otherwise, it used to work fine up until this new layer. I didn't change anything about it. Thank you for the quick response!
Wait, are you applying Color Vibrance to a pure white solid? What are you expecting the effect to do on a pure white solid? Because it's not going to do anything.
Oh my goodness that was terrible on my part. You are totally correct szalam! I fixed it now. Thank you all for your help.
