Shadowbox: A language file does not exist for your language: German (de). Tried to load: modules/addedmodules/shadowbox/shadowbox/languages/shadowbox-de.js. You can resolve this by either copying an existing language file and renaming the file or creating a new language file. Using either method you must use the 2-letter code for your language so the filename has the form: shadowbox-xx.js where xx is your 2-letter language code.
