I designed a customized 404 page and managed to set it as 404-default page in the theme options.
Unfortunately, when I test it, it doesn't show in the same design as in the page I layouted.
This is the version I built: https://penandbreakfast.de/da-ist-was-schief-gegangen/
And this is how it appears when I test the 404-page (for example https://penandbreakfast.de/lala)
How can I fix this?
Thank you and kind regards
