Not only, the upload logo page is broken, upload the logo for the desktop version, but for mobile version there is a smaller logo (who is a png, lol) and this smaller logo is untouched, and you cannot upload it from admin logo page...

We will look into this.

For now, you can use FTP to upload logo. Edit themes/default/header.tpl replace logo.jpg with logo.png
