  Can no longer run localhost debug site from Visual Studio for a .NET project
  
  I'm keeping an ageing C# .NET MVC website going that I didn't write. Things have been fine but a strange thing has just happened: 
  When trying to run the project locally from Visual Studio 2017 using F5 it has suddenly loaded up Chrome and immediately redirects to the www.mywebsite.com address in that window rather than the usual localhost:64874 address. 
  I can't work out how to stop it redirecting to the live website. It never used to do this and the only thing that seems to have changed is that I was using a different web.config temporarily to connect to a different database and Visual Studio said 
  'The page cannot be run in debug mode because debugging is not enabled in the Web.config file. What would you like to do?' 
  and I checked 'Modify the Web.config file to enable debugging'. 
  Since then Chrome fires up the www.mywebsite.com and nothing I do can make it go back to running localhost - if I type the localhost:64874 address into the debug Chrome window it redirects to the www immediately.
  I edited the web.config to 'debug="false"' and this makes it run but without debugging, which is kind of useless. As soon as I put it back to 'true' then I return to www.mywebsite.com. 
  I searched for 'www.mywebsite.com' and there isn't any mention of it in the entire codebase. There are no redirect rules setup anywhere I can see. 
  Any ideas? (I did look through similar questions but none of them were quite the same or solved the problem).
  edited web.config below:
