Background of the issue:
I created a custom 404 page in German and translated it into French for my site الرابط المخفي. I want both language versions to work correctly.
Symptoms:
The custom 404 page works in German, but the French version opens in the wrong language (German).
Questions:
Why does the French version of the custom 404 page open in German?
How can I ensure the translated 404 page displays in the correct language?
