I NEED HELP

When I tried to connect to my website I received this fatal error message. Is anyone familiar with it And knows how to fix this error. I HAVE ANOTHER WEBSITE THAT i CREATED WITH ELGG but its not having similar problems. need someone's help as soon as possible.

An unrecoverable error has occurred and has been logged. Contact the site administrator with the following information:

Exception #1349648710.

  • The exception number is a timestamp that gives you a hint when the error occured and had been logged in the server log. In human readable form the time/date is Sunday 7th October 2012 @ 22:25:10pm GMT. Check out your server log for entries around that time for more information about what's wrong.

  • Is this a new site, or did you transfer it from somewhere else?  I usually see that when I copy the codebase, including the settings.php but don't have a valid database yet.
