Who can I disable the complete editpage-copy-warn-section?

When I cleared the MediaWiki:Copyrightwarning2 Page, I have a big red line in that area, in edit mode.

That section should have a CSS class or id. Find it inspecting the element in your browser, and add a CSS rule (see Manual:Interface/CSS) to hide it (display:none)

Thank you, I need the $wgAllowUserCss setting. Well

Only if you're going to add the CSS in your user's styles. You can add it to MediaWiki:Common.css and it will affect all users of your wiki

I have my own use css, but the changes doesn't affect. After set this setting, it works
