Error: Just installed the new BlueSpice on my mediawiki. Everything seems to work but on the editing site I get real strange icons.
Solution:
"Just delete or uncomment in /resources/src/mediawiki.action/mediawiki.action.edit.toolbar/mediawiki.action.edit.toolbar.less this lines: mw-editbutton-bold {
.background-image("images/@{button-bold}");
} mw-editbutton-italic {
.background-image("images/@{button-italic}");
} mw-editbutton-headline {
.background-image("images/@{button-headline}");
} mw-editbutton-signature {
.background-image("images/@{button-sig}");
} "
