Suddenly, my local dev site's tabs have started linking to the live site. For example, when I view https://mysite.lndo.site and click the edit tab, it points to https://mysite.com/node/166. If I type in https://mysite.lndo.site/node/166, it still redirects me to the live site. This is a recent phenomenon, but I can't work out what change has caused this to start happening. Is there a simple setting I'm missing somewhere?
