Problem: The client added a custom language and encountered an error stating that content in this language cannot be automatically translated unless mapped to a supported language. Solution: We recommend duplicating the content from English and Arabic to the respective custom language. It is important to understand that automatic translation is not possible when the original language and the target language are the same. To resolve this issue, you should map your custom secondary language to your site's default language. For detailed instructions, please refer to our documentation on Using Automatic Translation with Custom Languages.
Please note that this solution might be irrelevant if it's outdated or not applicable to your case.
