"No input file specified" in metadata.php

When I try to access my metadata.php file, this message is displayed: “No input file specified.”

My client is using a GoDaddy shared hosting plan, which leads me to believe the problem is due to the possibility that the php-xml extension is not installed. I don’t know this for sure, and i am waiting for a response from GoDaddy to be sure.

Is the missing extension the only reason I would receive this output from the file or is there something else that I may be missing?

Thanks in advanced.
