Hi Fresatomica,
thanks for your reply. I have just tested if the error would disappear by using Twenty Twenty-One theme on my website.
Unfortunately, this didn’t fix the issue — the authorization header is still missing.
So I’m afraid changing the theme is not the solution to the riddle …
Especially since I need a theme which is GDPR compliant, without Google Fonts, I guess that’s not the case with Stow since it isn’t with Sela, is it?
Because Stow is already a child theme building another child from it won’t work. Really a pity.
Regards
Dinhac
