UBB.threads PHP Forum Software Community Forums UBB.threads 7 Bug Reports UBB.threads 7.5.7: scripts/adduser.inc.php gives error while registering a new user

your config.inc.php has 'wordsmith' instead of the user ID ( 2 ) for the main admin id... not 'ID' and not 'name' in primary settings

so it has nothing to do with mysql. that is a valid error and it tells you what was wrong too
