Heya! Around the middle of the imports, it has this line: @import "/load.php?mode=articles&articles=u:dev:MediaWiki:ModernWikiActivity.css&only=styles";

That doesn't go on ImportJS, instead you'd have to put it on Mediawiki:Common.js. (Note: After saving your changes there, you'd have to click "Submit for review" on the side).
