Forum:MyPage-Wikia.css issue

Hello, A user in my wiki asked me about CSS that will change the user page header color. The CSS was this: BsyewCSSUserHeader.png, as i checked in my test wiki. I also tried to check if it would work when adding to the Developer Tools using F12, and it also worked, but i can't figure out why it doesn't work in Special:MyPage/Wikia.css.
