ummm what does this mean?
You chose to install in the main directory of the domain
www.xxxxx.co.uk, but there are conflicting filenames, therefore we can not proceed. Following filenames already exist in the main directory of the domain xxxxx.co.uk (path="/home/xxxxx/public_html/").You must manually remove these files before proceeding with auto-installation:
index.php
How do i manually remove files?
