Hello Kevin<br><br>And a user id 1, is there one ? Could it be that someone/something changed that, a 1 to 0 ?<br>I've already asked around, and the usual suspects all say that didn't change<br>anything, and the logs agree with them...<br>

it probably has the same error. That means getting the tape from two days<br>ago, which is going to take some more time...<br><br><br><br><div class="gmail_quote">On Wed, Aug 24, 2011 at 2:48 PM, Kevin Falcone <span dir="ltr"><<a href="mailto:falcone@bestpractical.com">falcone@bestpractical.com</a>></span> wrote:<br>

</div></div>I'm not aware of an RT version that had a User ID 0.<br>
Sounds like someone renumbered your RT_System user manually in the<br>
database, or that you have database corruption.<br>
<br>
You can try taking a backup and fixing this manually, but if it is<br>
corruption, there may be other problems.<br>
