You might start by carefully examining the plog-config.php paths that you have done the installation with, and ensuring that they match your actual environment. Also, since it looks like you might be using IIS, double checking your local path (C:\Inetpub\vhosts\goughsfashions.com.au\httpdocs\fascinators\gallery\plogger.php) might give some better clue as to whats going wrong.
