Thread:Extension talk:VisualEditor/Broken after upgrade to 1.25/reply (3)

I had this issue on a fresh install of mediawiki 1.25, set up to be a private wiki. It was fixed by setting this variable in LocalSettings.php:

$wgSessionsInObjectCache = true;

Note I already had this enabled: $wgVisualEditorParsoidForwardCookies = true;
