This site, degrandchamps.com, has been up and running for a couple years now. Suddenly about two weeks ago the www URL quit working. When trying to access the site using www it returns a 404 error. I have researched and tried so many things I can’t even begin to start at what I have tried. I am getting pretty desperate as this client is quite frustrated. There were two errors at first. The one I corrected was that the www suddenly started returning that it wasn’t secured. I fixed that by reinstalling certbot and the certificates. This is a Wordpress site on Ubuntu 16.04 with Apache 2 installed.
