I am sorry, but not all the pages of the wiki have been translated in all languages.
Please refer to the English page (Or French, Italian, or any other available language you feel comfortable with) or ask here your question.
If the language you need cannot be opened using the link you showed in your pic, please use the Language dropdown list at the bottom right of the wiki page.
Note for toubleshooting: Interlink provided to redirect to the Eng page of an untranslated page of the wiki gives an error.
See e.g. https://wiki.geogebra.org/p... and click the link provided in the work in progress box.
You get an error page on redirect.
