I had shared Rays note above with our IT people and received a reply that : "For the support.localhost, there was a missing HOST config. Should be good now.. Maybe it will even help with your dreamweaver problem"
However it did not solve the Dreamweaver issue. This is where I am at this point ... Hopefully the pictures will show in the correct order. to tell the current story.
The changes made by our IT person does allow http://support.localhost to work in Edge, Chrome and firefox, each stating that the site is Not secure. However does allow me to accept and go to the home page but they don;t recommend it. Same message as any site without an SSL you come across. But they work.
In Dreamweaver when I open a page and try to view the tables i still do not get them but we see different results. When opening a page I get a message stating to dynamical discover the page. Which I do then I get an pop up stating My certificate doesn't match (see pic)
I choose yes to proceed then get a new message ...
"This page has server processing directives the design view cannot display/ Switch to Live view" (see pic)
When I choose live view I get a similar screen to Design view.
My IT person says he has set up everything correctly.
It seems like I am getting closer to a solution but one thing is blocking it from working properly.
Does this give you any new ideas Ray?
