X frame options set

[Bernie_O]

Apparently removing the x-frame-header from the nginx website configuration removes the warning from the admin-section. The header seems to be added by Nextcloud anyway:

X-Frame-Options "SAMEORIGIN": NC on nginx keeps warning me

I had the same issue on debian. It seems that the SAMEORIGIN header is already added to by the nginx configuration somewhere. When I remove it from the nextcloud server configuration it is still added and the error goes away.
