Access Stats - Server error 500

Hello

I'm having trouble getting anything out of this script.
Whatever i do, i get the Internal Server Error 500.
What could this be?

My stat.pl looks like this:

# url to script
$cgiurl = "http://www.autoplaza.no/cgi-bin/stat.pl";

# url to the image files without trailing "/"
$gif_url = "http://www.autoplaza.no/stat/gif";

# path to the log files from the server root without trailing "/" (chmoded to 777 (drwxrwxrwx))
$base_dir = "/local/www/virtual/www.autoplaza.no/data/stat/logfiles";

# url to the log files without trailing "/"
$log_url = "http://www.autoplaza.no/stat/logfiles";

I've set everything to 777 but that didn't help either.
Please help.
