Acces stat = 500 internal error

I edited and uploded acces stat to my website.

I think all path is correct:
$cgiurl = "http://kepeslap.alien.hu/cgi-bin/stat.pl";
$gif_url = "http://kepeslap.alien.hu/gif";
$base_dir = "../logfiles";
$log_url = "http://kepeslap.alien.hu/logfiles";

CHMOD for logfiles is 777, cgi-bin 755, gif 755, ip.log 666 and *.pl 755.

When I try to saw my stat I got 500 internal error. Whats the problem?

i think u should change $base_dir = "../logfiles"; change it in $base_dir = "/full/path/to/the/logfiles";

I edited $base_dir but know i got 404

$base_dir = "/home/webhosting/kepeslap/public_html/logfiles";
