I've just moved a site from a cPanel to LPCP set up.  I've manually  uploaded all my files as instructed into the public html but I need to put my own index.html file to replace the lunarpages placeholder index.html.  In cPanel there was a nice simple box to check to replace same-name files when uploading but I cannot work out how to replace in LPCP File Manager.  I just keep getting an error message.

I've gone through the LPCP wiki articles, sat through the video tutorial on File Manager and found nothing about this.  Nothing in these forums either when searching for replacing files.

Please can someone walk me through how to do this in LPCP File Manager?

Thanks.
