Sidebar Toolbox issue

From semantic-mediawiki.org

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.

Cannot reproduce this. Try clearing the cache.

I found the problem. It seems that something is not working like it should in the Vector skin. On a computer and tablet, on which I never visited this site, using Opera & Firefox the toolbox menu also disappears after the page is loaded. When I change to the Vectorata skin the toolbox menu stays visible. I can't remember if I changed to the Vector skin manually in the past or that the default skin changed. Using the Vectorata skin now. Regards.
