I have just updated apache/php from 'Apache/2.0.47 (Win32) PHP/4.3.3' to 'Apache/2.2.11 (Win32) PHP 5.2.9-2' (Note: fresh install of both).

I moved the contents of htdocs from my old apache to the new one. All has gone well except there is a single *.php file that cannot be accessed via the browser through apache (using http://localhost/sher/). I have no index file atm so i can see the list of all the files in that location. All are there, and all work if selected except for one. Apache acts as if the specific file doesn't exist. I've tried copying, renaming the file, pasting the code into a new file, but no matter what I do it still can't see the file when its accessed. The problem occurs with all web browsers i've tried (Opera, IE and FF). The file had no issues with my previous setup of Apache/PHP, I've been scratching my head for a few days now, any ideas?
