how can I change the display language of the site for all users to Arabic? I mean, I want the user interface to be for all users from right to left. I want users to see the right-to-left interface when they enter the site. As in the attached picture. Thank you
To prevent users from having a different language, the go to Site Settings / Language settings / Show advanced settings and make sure that there are no other "available languages",also called Alternate languages.
When a user visits a site, SharePoint will check the language(s) in the user's profile. If one of them matches the alternate languages or the site's base language, that is the language that is used for the interface. For Arabic, Hebrew, or Dari, that sets the right-to-left direction of the layout. If there is no alternate language, then displaying in other languages is not an option.
You must be signed in as a site owner or site collection administrator to choose language settings for a site. In addition, if you are using SharePoint Server, the SharePoint administrator must first deploy language packs for the languages you want to use. There is no need to install language packs for SharePoint in Microsoft 365.
1.From a site page, click Settings Settings button from SharePoint Online, click Site Settings. If you don't see Site settings, click Site information and then click View all site settings. Some pages might require you to select Site contents, and then Site settings.
2.On the settings page, in the Site Administration section, click Language Settings.
Note: If the Language settings link doesn't appear on the Site Settings page of your SharePoint Server site or site collection, then language packs haven't been installed. See your SharePoint Server administrator.
3.Select the languages you want to make available:
If you are using a communication site and you have page translations enabled, select languages by typing them or using the dropdown for each language. For more information on how to do this, see Enable the multilingual feature for communication sites and choose languages.
If you're using a communication site without page translations enabled, or using a Team site or a classic site, select the check boxes next to the languages you want to make available.
4.If you want to overwrite site translations in the site interface, select Yes under Overwrite Translations. If you're on a communication site with page translations enabled, select Advanced and then select Yes under Overwrite Translations.
Now your users can change the display language for their personal use of the user interface. Learn how users can change their preferred language in Change your language and region settings.
After you turn on alternate languages for your site, you can create new lists or libraries in one language, then display the site in a different language, and modify the list or library name for that language. The same process works for list and library columns, and for navigation links.
