Ok... this is a long shot, but seeing if anyone has advice - I'm a bit of a dilettante. I have a few sites/apps published here from a few years ago with multiple domain pointers. The nicest one still relevant is http://bigbytes.mobyus.com/commute.aspx Now have a new project idea - In Visual Studio I created a new empty (default) Asp.Net app. When I publish to my domain (in a subfolder with domain pointer) none of the CSS comes through. Seems to be using bundles and that functionality is not executing properly. Works fine locally in debug/IIS Express. Could be because root app is in 4.0 and new app is in 4.7.2, but - When I publish the new app to the root rather than the subfolder (to see if the web.config or setup of the root app is the issue) I get a different security error and it won't run at all in the root. The root is mobyus.com - the new domain with the new app is karmador.org which lives in a subfolder. Let me know if any tips on this. Thanks so much.
