Why aren't custom cursors working for me???

Hello folks! So, here's the situation: I copied and pasted a custom cursor layout into my profile and it's not showing up! I then tested the code on a SpaceHey CSS preview website thing, and it worked perfectly! So, why isn't the cursor showing up for me? Is it the computer? Or something else? If anyone knows, please comment down, I really want that star cursor to show up for me, thanks :]

Edit: I found out that if I'm on someone else's profile and they have a custom cursor, it does work for me, I just can't see the cursor on my own profile, which is sad
