The readers of the German Wikivoyage decided to switch the desktop skin from Legacy Vector to modern Vector. I think the following parameters has to be set:
$wgVectorDefaultSkinVersion = 2 wgVectorDefaultSkinVersionForNewAccounts = 2
Please set the default vector skin for users who have not made a preference selection, too.
The result of the survey can be found on https://de.wikivoyage.org/wiki/Wikivoyage:Lounge#Umfragen (first topic "Skin")
- Deploy modern Vector skin as default on dewikivoyage
