Thread:Semantic-mediawiki.org:Community portal/Sidebar Toolbox issue

I noticed that on this website the Toolbox menu in the sidebar is empty after Log in. You see it being built but then it disappears and it only shows Toolbox. When logged out the Toolbox menu is ok. I know for sure this was working a while back. Is there a problem with the side or am I missing something here? Using Firefox 19.0.2 Beste regards.
