Why is the Wayback Machine showing a 403 hidden error? How to fix it? or Getting a 'wayback 403 hidde

Yep, getting it too. Wayback 403 hidden is usually a block, not a bug.

Some sites actively prevent archiving.

You could try the Wayback Machine’s beta interface (beta.waybackmachine.org)—sometimes it behaves differently.

Or dig up the page on Archive.today if it’s there.
