[rt-users] Error, couldn't load 0 from the users database
Hello all, We are having a problem with our RT install, after a few years of almost flawless service, today we noticed that emails weren't being sent. We are using version 3.4.5, on Linux (FC4, MySQL 4.1). The web interface works just fine, we can login, create/modify/close tickets, etc, but no emails are sent. There is no apparent problem with the machine or the MySQL database, and this is what appears on the RT log: [Wed Aug 24 12:23:50 2011] [err]: Couldn't load 0 from the users database.

Sounds like someone renumbered your RT_System user manually in the database, or that you have database corruption. You can try taking a backup and fixing this manually, but if it is corruption, there may be other problems. -kevin pgpKXMaYLAgmi.pgp Description: PGP signature RT Training Sessions (http://bestpractical.com/services/training.html) * Chicago, IL, USA September 26 27, 2011 * San Francisco, CA, USA October 18 19, 2011 * Washington DC, USA October 31 November 1, 2011 * Melbourne VIC, Australia November 28 29, 2011 * Barcelona, Spain November 28 29, 2011
Re: [rt-users] Error, couldn't load 0 from the users database
Hello Kevin And a user id 1, is there one ? Could it be that someone/something changed that, a 1 to 0 ? I've already asked around, and the usual suspects all say that didn't change anything, and the logs agree with them...

Thanks Kevin, it was exactly that, I changed the ID from 0 to 1 and everything seems to be working now.
