Hello, WIWOSM is activated now, but if it not work in your language version of Wikipedia it can be that the article name will not transfer from Wikipedia to map aplication. Check this on articles like "Berlin".
For repair this there are two ways: *Add the article title to the URL of the map inside MediaWiki:Common.js: + '&title=' + mw.util.wikiUrlencode( mw.config.get( 'wgTitle' ) ) *Better way seems the installation by using Metawiki: http://de.wikipedia.org/wiki/Hilfe:OpenStreetMap/en#Installation This keeps you up-to-date and clean-up your local javaScript.
