Problem: The client was experiencing an issue where the dashboard language in Arabic was not changing to English, despite the language settings being adjusted. Solution: We recommended the client to check and configure the Language option in their WordPress Profile. Specifically, we suggested unchecking the "Editing language" setting, which resolved the issue, allowing the dashboard to display in English while set to Arabic.
