Really? So this means I might also have another problem?

Here is the output from running your three test queries on both dbs. The
last two return more than one row on both machines, and the last one
returns twice the number of error messages on the test db than on the
live db.

I find it strange that the last query produces 1 error message on the
live db but 2 on the test db ... I can't see any reason for this.
