 * Hi,
 * at the moment Im writing a plugin which needs database access.
    I tried to use
   the wpdb-class and have already set $wpdb global.
 * Here’s the code:
 * <–snip–>
    function foo() { global $wpdb; $wpdb->query(‘SELECT * FROM table’);}
   foo(); <–snap–>
 * This Error returns:
    “Call to a member function query() on a non-object in[..]”
 * Thanks in advance.
