One PC won't show my website at new host - all other PC's do show it
Ten days ago I changed the hosting company for my website. Everything went well except that one of the three computers at home refuses to point towards the website at the new host. It continues to try to point at the old host, showing a frozen website page until it was removed today and it now just shows a blank page.
The problem is the same with Firefox, Pale Moon and Internet Explorer browsers on that Windows 10 PC. I have tried all the recognised methods of clearing browser caches, history, flushed DNS etc etc. In desperation I uninstalled and reinstalled Firefox with no change. Friends all over the world can see my website with the new host - it's just this one computer at home that refuses to do so. I can only think there must be a registry item causing this but which one? Ideas welcome!
