I'm trying to create a page where there is tabbed content, specifically, making an easiliy readable article for the complete timeline and anime timeline of the Toaru Majutsu no Index. Tabview extension failed me since it doesn't seem to work or it seemed to be uninstalled despite being turned on by "default", while the tabber extension doesn't work because it removes header 3 and header 4 when published, screwing up the layout. I tried to add codes to the end of MediaWiki:common.css as instructed by the community Wiki but it doesn't seem to work.

Is there anyway you can reinstall or reactivate the Tabview extension?
