Someone trying to hack my site... MySQL Error
 

I recieved 5 of these errors last night all at the same time...

Code:

The IP address are different on all of the, but other wise the error is identical. What has me concerned is it is saying "User orgadmin". There is no user on my site by that name. Also, what does the /includes/class_core.php file have to do with this?
