Marincky. Thanks for your efforts !
Incidentally, when I enter my domain temporary URL, http:74.86.118.24/master username, I am immediately linked to a page stating 'Apache is working on your CPanel and WHM server'.
So, 74.86.118.24 doesn't work, 74.86.118.24/cpanel doesn't work, yet 74.86.118.24/masterusername/ at least takes me somewhere even if it's not quite what I expected to see !
Not sure if this helps or just further confuses the issue ? David.
