Thread:Project:Support desk/Sidebar menu does not update after upgrade to 1.23

Hi.

Wiki url: http://veiskillewiki.laiv.org/

Version: 1.23.0

I've recently upgraded the wiki from 1.20 to 1.23. Everything went pretty much as expected, but the Sidebar now show the default set of choices, and it does not seem to react to changes to MediaWiki:Sidebar

http://veiskillewiki.laiv.org/MediaWiki:Sidebar

I've tried purging pages, touching LocalSettings.php, truncating the objectcache table and set $wgUseDatabaseMessages to true as described on Manual:Interface/Sidebar, to no avail.

Any assistance on this would be greatly appreciated.
