thank You, Johannes,
but I think we can skip this,
we reduced the query statement to the most simple one:
"SELECT * FROM {tablename}"
if the tablename is wrong, then another error message is issued.
the result is not treated by a while-loop but just by fetch_num_rows,
which at least reports the error.
(and, by the way, the same script runs on another system)
so we are more looking for problems with apache versions
and/or modules.
we also checked access-rights, but this also causes different errors.
any other idea?
