okay, I just tested on a new install of the latest version and had no issues with it showing up and it was only a couple of clicks to get to do so. So let's work thru your issues, just to be sure you didn't do what I often do, you did SAVE the page? So if you go back to that settings page, now the logo you upload shows in the Store Logo box?
Perhaps since you are new to this cart, the way the resource library works is an issue, it took be a bit to learn to use it when I started with Abantecart over a year ago. And with this 1.2 version that have changed how the resource file works a bit and I am getting use to it also.
Please keep testing out, I think you will come to love it.
