I had done the search and left only table where it says TABLE_CONFIGURATION, this says table at the other modules as well I believe this table does not refer to the file name. I believe the Line $db->Execute("insert into " . TABLE_CONFIGURATION . " (configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, set_function, date_added) VALUES ('Enable Express Method', 'MODULE_SHIPPING_EXPRESS_STATUS', 'True', 'Do you want to offer express rate shipping?', '6', '0', 'zen_cfg_select_option(array(\'True\', \'False\'), ', now())"); is the problem, I compared this line to other Execute lines to other modules I can not figure out the problem.
