ui-icons_888888_256x240.png is not found. Disabled button icons are normally seen when activating an edit.
Code from toolbarbutton.css:
.wikibase-toolbarbutton-disabled .ui-icon {
background-image: url(../../../../../../../../resources/jquery.ui/themes/default/images/ui-icons_888888_256x240.png);
Relative path is incorrect due to new Wikidata extension path that moves Wikibase down two additional levels from root. Problem is how to make Wikibase relative path independent of Wikidata extension.
