<?php
	if(is_file($_GET['file'].".php")) { include($_GET['file'].".php"); }
	elseif(is_file($_GET['focus'].".inc")) { virtual($_GET['focus'].".inc"); }
	else { virtual("news/news.inc"); }
?>

That code throws this error:

Warning: stat failed for .php (errno=2 - No such file or directory) in /usr/home/edgewww/helpandsupport.net/cs/htdocs/index.php on line 39

Warning: stat failed for .inc (errno=2 - No such file or directory) in /usr/home/edgewww/helpandsupport.net/cs/htdocs/index.php on line 40

I've corrected this issue by using file_exists but for the sake of not having to change my backend, I'd love for is_file to start working again.
