Hi there, I am getting the same problem too..
Warning: require_once(../wp-config.php) [function.require-once]: failed to open stream: No such file or directory in /home/graceong/domains/graceong.com/public_html/wp-admin/update-links.php on line 2
Fatal error: require_once() [function.require]: Failed opening required ‘../wp-config.php’ (include_path=’.:/usr/local/lib/php’) in /home/graceong/domains/graceong.com/public_html/wp-admin/update-links.php on line 2
I don’t get what is wrong with the wordpress ever since i upgraded it to 2.5
