Using Foreground and VisualEditor
If you would like to use the Foreground skin together with the VisualEditor extension you will have to add it to the "$wgVisualEditorSupportedSkins
" configuration parameter in your "LocalSettings.php" file after the inclusion of the VisualEditor extension:
$wgVisualEditorSupportedSkins = [
'foreground',
'vector'
];
Note that in case you are only using Foreground on you wiki you do not need to have 'vector'
to the array mentioned here.
