here is the exact errror i get when try to build all :

Backing up database . . .
Backing up links, category and email database (File::Copy) ...

CGI ERROR
==========================================
Error Message : Unable to copy links backup. Reason: Bad file descriptor
Script Location : /usr/home/uptown/public_html/undersites/admin/nph-build.cgi
Perl Version : 5.00404


And when i try to click on a link it starts to download jump.cgi(the permissions are right too.)

Perhaps the thread at http://www.gossamer-threads.com/...um2/HTML/000691.html might be of some help to you.
