I can't upload skins from the Minecraft Launcher. A few months ago I had an issue with my computer and I had to format it. I had to install everything again including Minecraft. Before this, I had uploaded skins with no problems. But, every time I try to, I get a message saying "unable to save skin". I've tried logging out several times, as I saw in similar posts, but it didn't solve my problem. I've also tried with several skins, just in case. I can change my skin from minecraft.net, by the way.
