A note on upgrading[edit | edit source]
I've done the upgrade myself, and though fairly straight-forward I suggest you start fresh and move back images/*, LocalSettings.php and then re-install any plugins you want to use. Some are not compatible with the new MediaWiki version, and others will need updates to work.
Running on Apache[edit | edit source]
In order for the VisualEditor to work properly on Subpages you need to add
AllowEncodedSlashes NoDecode to your vhost config.
