I get warnings every time the random ifarchive mirror I get is ifarchive.smallwhitehouse.org. I was posting here in hopes that the owner might see.
What warnings? I see nothing out of the ordinary.
On Chrome it gives a red screen saying it may be unsafe.
I don’t see that in Mac Chrome (66.0.something).
ifarchive.smallwhitehouse.org/ is an HTTP server, not HTTPS. Maybe that’s what it’s trying to warn you about? HTTPS-everywhere is a noble goal, but a lot of old servers don’t support it and that’s going to remain true. (And it doesn’t matter for a static, public web site like this.)
