so i have a multi language website and some content ( English version ) are not available in the arabic version so if a user is currently on that particular page and he switch the language he will get an error so what could the solution be ? thank you in advance
Using the default language version for untranslated pages
You can configure websites to display content from the default language for documents that are not available in the selected language.
Now you can sign out and view the French version of the live website again. Documents that are not available in French are displayed in the default culture (English).

i dont want any service to translate them i simply need to add a default page in case any broken link happens it shows up something similar to 404 pages
This isn't a service. It's your own content..
You just have to enable the setting and pages that are not translated will default back to your own "default".
check the Multilingual section on this info page: https://docs.kentico.com/k10/configuring-kentico/managing-sites/configuring-settings-for-sites/settings-content
Combine with default culture - Indicates if the default culture version of pages should be offered for pages that are not available in the currently selected language.
