Why do I keep getting this? I thought it was something wrong with Opera, but Safari does it too. It's been like that for two days now.
 
It might be a certificate problem that is now present across Apple OS's:

So I looked it up. A VPN is a Virtual Private Network. I don't know if I have that or not. My internet provider is Xfinity, and my router is a Motorola MG7550. I've never had this problem before.

You don’t have one. They’re either paid VPNs or free VPNs. Express VPN is one of the better ones by the cost.

The website has a valid HTTPS certificate with an intermediate certificate from "R3" and a root certificate from "ISRG Root X1".

Most root certificates should be pre-installed on you machine as part of the OS. See "System Roots" in Keychain App . I assume the error message means you machine is lacking the needed root certificate, as a consequence the certificate chain is broken and the site is not trusted.

A possible solution is to click the "lock" icon in the address bar and inspect the certificate chain. Any certificate that comes up as untrusted can be marked as trusted. It is also possible to install a missing (root) certificate in you certificate store.
 
Here is an important reason to avoid ExpressVPN:
 
R3 certs are via Lets Encrypt if I mind right, Lets Encrypt's main cert is expiring/expired and presumably will be updated soon. We are preparing for weirdness at my company due to this issue and expect it'll fix itself. But that isn't to say you can rule out a issue on your machine.

I heard about this issue on the news, they said macOS 10.12 Sierra and older will be affected. I am running macOS 10.12 Sierra on a MacBook5,1 and using Firefox most of the time but Safari seems to be working fine as well. I am yet to see that "your connection is not private" warning.

I didn't know that about ExpressVPN, kinda surprised me. My subscription is up in February, will probably move to NordVPN or another viable provider.

I had the same problem. I had El Capitan on my Macbook Pro 15 mid 2012. Upgrade to High Sierra was the solution.
 
I use TOR when I don't want my ISP to record my depravity ;) don't pimp yourself out to the FOTM youtube video bankroller.
