Hi,
There seems to be an issue with opening certain files in the browser. Im using Chrome, Microsoft 10.

• Static pages 2 out of 9 have problems:
  1) works in preview but when open in browser - it goes to file explorer - see screenshot
  2) has the layout ejs icon but is an html file- see screenshot - when open in browser get error message - see screenshot
• Dynamic page based on a layout similar to static 2 above in that get error message when open in browser - see screenshot,
