CSS is basically the visual style of the subreddit (font, background, colors, etc.) While I don't know how to remove it, the claim of it being "stolen" seems to be odd, unless he shared the code with a mod or something along those lines and they implemented it without asking
I used to be the head CSS mod for this sub until this morning.
Ah, I see. I thought that other guy was the only other mod besides Niall, Chris, and Ding Dong, hence my confusion. I wonder if Chris removed you thinking that you were one of the newer mods added?
Im not sure honestly.. i sent them a message and no response.
it was not saved, that's the problem I had so much progress since the last backup, everything is there, the notes, chords, playlists, channels, but when I play something only white noise plays. Other projects work fine
You could try to use CTRL + ALT + Z over and over. I have saved FLP's this way in the past.
