I get a warning:
arning: Invalid argument supplied for foreach() in /websites/dkpsystem.com/admindkpupload.php on line 226

and no items are shown.

Also is there a way to delete a raid from a dkp system? I imported a snapshot into the wrong system now I can't get it back out.

I'll look into the error for you. Thanks for letting me know.

As for deleting a past raid, head to Admin > Raid Attendance, click "Edit" next to the raid you wish to delete, and click "Delete" at the bottom of the page.
