It only works on project pages though, not profiles. That's why I was confused how you got the font xD
You also have an "edit theme" button on your profile page!
I've used that, and when selecting 'text font' I've selected pixel which doesnt work. It instead looks like Lato (on the actual page).
Then I cannot help you, for I simply don't know. 😔
Thats okay, thanks for the help with the itch pages though! :D
