My install of Nextcloud 12 comes up with the following security warning:
The “X-Frame-Options” HTTP header is not configured to equal to “SAMEORIGIN”. This is a potential security or privacy risk and we recommend adjusting this setting.
I’ve been trying to figure out how to update the headers, but am running into very complicated seeming advice that hasn’t worked for me so far.
Any ideas on how to go about fixing this?
