Hey Brett,

Actually that was not a bug, just that system can't find out this user ID - 457 on discussion page, you can take a look of my screenshot below.

For some reason this user ID get deleted from admin, so causing this warning message shown out on your page.

I have temporary assigned another user ID in that reply, that warning message shouldn't show out now.

In my suggestion, you have to install this plugin `user - Easydiscuss` so that if the user get deleted, it will assign back all his discussion to your Superadmin ID (you can download from http://stackideas.com/downloads/plugins ) - All EasyDiscuss Plugins - After downloaded - extract it - then upload that plugin as i mentioned just now. Hope this help .

Thank you! I installed the plugin as directed, but the warning message is still there.

BB:)
