Installation Details: SuSE Linux 7.1 kernel 2.4 + apache 1.3.14 + php4.0.4pl1-1 + mysql 3.23.30-2 The following error message appears: "Warning: Supplied argument is not a valid MySQL result resource in /www/wp/php/login.php on line 29" Remarks: php4 runs fine and returns "not FALSE" for function mysql_db_query (means query is ok) or mysql_query. But the result of the query causes the error above. Any other function using the query-result does so also. The same php-script runs fine on other systems with the same environment. The Access-Rights are completely "open" for the whole development site and all of the mysql-users have full access, there are only a few test-records in the table (no question of size!). Can anybody help us with this problem?
