Hello, I have two problems that, I guess, have common cause. My mediawiki is at: arhelium.pl/mediawiki/ (I made it appear in English so that you could look at it, even though pages are in Polish). My page is on a shared host. Here are the current versions of extensions that are used.
The two problems are: Searchbox isn't appearing in the left sidebar, even though the link is in the source.
Second one, is vector extension is not working, even though, one can clearly see that it is installed .
What I want to work is: searchbox that offers hints, and collapsible tabs in the left sidebar.
Only more information I could give you is the one generated by mediawiki on the update page:
