that path C:\inetpub\vhosts\hair-for-men.com\httpdocs\ is the full path on your remote server (must be a windows server).
I would look near line 130 on confirm.php. I would guess that you left a blank line between a closing php tag and the next opening php tag like this
remove any blank lines this that are outside of the php tags. That is what is triggering your error.
