So I've got to edit my 404 page. Since my client's website has 5 languages, I'd like to let him edit and translate the 404 page by himself, with normal WordPress editor. Also, we're currently using Polylang as the localization plugin.
Is there a way to have the theme's
404.php as a regular page?
I've tried to create a page and then assign it to the 404 template via template name, but it doesn't work, because it seems that
$post is not available inside the template, so I cannot write contents.
