I get this error randomly at least a half dozen times a day: 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
It has occured when I have tried to submit comments, refresh the page, on login, when logging out, while in the administration panel, etc.
The problem began when I upgraded from 2.2.3 to 2.3, until then it had never occured, and has carried over to 2.3.1. I've tried reinstalling files several times and even did a complete reinstall of WordPress twice and I'm still getting the error messages.
