CGI ERROR
==========================================
Error Message : Unable to copy links backup. Reason: No such file or directory
Script Location : C:\XITAMI\cgi-bin\links\admin\nph-build.cgi
Perl Version : 5.00307

My pahts in links.cfg :

# Paths and URL's to Important Stuff
# --------------------------------------------------------
# PATH and URL of Admin CGI directory. No Trailing Slash.
$db_script_path = "C:/xitami/cgi-bin/links/admin";
$db_dir_url = "http://127.0.0.1/cgi-bin/links/admin";

# URL of User CGI directory. No Trailing Slash.
$db_cgi_url = "http://127.0.0.1/cgi-bin/links";

# PATH and URL of Pages to be built. No Trailing Slash.
$build_root_path = "C:/xitami/webpages/links/pages";
$build_root_url = "http://127.0.0.1/links/pages";


I think all is good, but no run.
