Recieving errors when accessing my pages

About every other time I access http://mlmsuccessbunney.com, I get this error. I can refresh it and it works fine.

Warning: main(../wp-config.php) [function.main]: failed to open stream: No such file or directory in /home/bbunney/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/bbunney/public_html/wp-admin/update-links.php on line 2

About every other time I access http://skinnyandhealthy.com, I get “wordpress disabled” error. I can refresh it as well, but people looking for or at your sites won’t do this.

Does anyone know whether this can be fixed? I use hostgator for hosting
