Say, do you see any custom CSS anywhere? I mean, I'm not even sure which magazines use it anyway, do you see something on /m/pamasich? Besides the test banner, I also made the magazine name in the sidebar red.
If you don't see anything changed there, do you maybe have custom CSS turned off? In your settings, there's an option Ignore magazines custom CSS under a text field that lets you enter personal custom css. Make sure that's not checked.
