WampServer

I have been using WAMPServer 2.0i for more than a month now without any issues.

But i started getting a `page not found` error for a specific page(getchatdata2.php). The rest of the site works fine.
getchatdata.php works fine(it is in the same directory)
I have checked the spelling and location of the files and everything seems fine.

My apache log file is as follows:
