Thread:Extension talk:Scribunto/Lua error: language code ' lang ' is invalid./reply (5)

Hello, thank you - I guess undeletion was just a try in the past.

Now the Script error problem disappeared, but still the license template is broken.

Per instruction from: https://www.mediawiki.org/wiki/Extension:UploadWizard I have imported required templates from Commons. Unfortunately, I have to say that MediaWiki is years behind the user-friendliness of Wordpress both in terms of installation, extensions and the whole interface. I am disappointed working with it for a while, but too late to change it.
