I had a 128x128 texture for a while, and decided to upgrade. Now, when I upload the texture, it doesn't show anything on the texture page. When I go to the game, it shows my old texture. I've sold my old 128x128 head, so I don't know what's going on.
EDIT: I only tried it on my head before. I just tried a different part of the body, that part doesn't work either.
The image for my head is this

Same with me, i can't use my 128x128 picture either. it's not letting me.

That's like fourth or fifth case of the same problem, which leads me to believe upload is borked. I'm also unable to download attachments, so the conclusion I come to: it broke.

This happened before. We'll have to wait it out till it gets fixed :F

I also can't upload my 512x512 head texture. I've been trying since yesterday (2nd October 2014). I'm using a 512x512 JPG data.

I made sure that it is activated and that my graphic settings enable showing body textures, it still doesn't work.

Good job guys, it's fixed.
