My guess is this is a warning generated by a library trying desperately to reach the webmaster.

The server response header needs to be fixed:

permissions-policy: camera=(), microphone=(), geolocation=(), payment=()

It's just really funny/confusing because now visitors to the site are seeing it, and the message is not meant for visitors.

It works in Safari because Safari does not support the header:
