Here's my problem: My head isn't showing!
I'm an old-schooler and my head worked in the previous versions, and when i updated it wasnt showing, not even a week after.

I have asked others if it was showing, and i was told it didnt show, so i tried reuploading it (.jpg), and here i am, 3 weeks later, without a head..

Halp!

add a colored pixel perferably red or green in the bottom right hand corner of your texture

Ah, so it's comparing my old and reuploaded head?

Well if you try reconverting it to tng. that might help, even redownloading toribash could help. But most of it all, some heads will not work, if so recreate another one a little bigger but it has to be 128x128 photo.
