Error upon login

When I try to login to my blog I’m greeted with the following message: Warning: main(../wp-config.php) [function.main]: failed to open stream: No such file or directory in /home/iyf500/public_html/wp-admin/update-links.php on line 2

Fatal error: main() [function.require]: Failed opening required ‘../wp-config.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php’) in /home/iyf500/public_html/wp-admin/update-links.php on line 2
