Fix extension and update them.
Fragment of a discussion from User talk:Wmat
I've installed Scribunto but haven't tested it yet. I've installed the Echo extension. And wikieditor works for me. Try clearing your cache before editing a page, as sometime wikieditor won't show up.
SimpleAntiSpam is already installed.
LocalizationUpdates is installed now.
You'll have to give me some time to finish upgrading the other extensions.
Cheers
