Timeline broken by MW Upgrade to 1.22
From semantic-mediawiki.org
Fragment of a discussion from Help talk:Timeline format
Further info: Loading the problem page indicated above also breaks the Vector skin collapsible sidebar menus (The separate Vector extensions have been removed for MW 1.22 per the u/g instruction). The collapsible sidebar menus work fine everywhere except on this one page.
Might not be that much of a help but we've upgraded from 1.21 to 1.22RC3 this week, using SRF 1.8 too and we don't have any of these issues, as can be seen there: http://www.entropiaplanets.com/wiki/EntropiaPlanets_Wiki#EntropiaTimeline
