NGINX Configuration

Need assistance on NGINX with WHM/Cpanel. 1. I have a VPS with root 2. I have cpanel/WHM installed which places new accounts in one directory 3. I installed NGINX which works but is expecting in another directory 4. I tried changing the [login to view URL] file to point to correct directory but end up with 403 permission error 5. Online documentation sucks! 6. Each account appears to have it's own permisson 7. There is only 1 active domain on this 8. There is another domain I want to make active but can't till this is resolved I have an idea what I need to do but I am concerned I would cause a vulnerability in the system. I know I am close but need help on this and need documentation on what was changed to make this work.
