Reader view often works.

Yeah, just turn on reader view. I get that exact message on some news sites, turning on reader view lets me read the site without disabling my adblocker or VPN. When I realized that’s all it took, I just set those sites to always use reader view.

I’m running: 1Blocker, AdGuard, AdBlock Pro, Consent-O-Matic, Ghostery, Vinegar, SuperAgent, and Hush

I literally just tried to fix this and I think it worked. I went to Safari's settings - advanced - disable JavaScript

Seems to have fixed it for me.

I just tested one website though, so we'll see.
