Did you make all new Product Types or did you just rename things in the product_types table?
IF you just renamed things, do you intend to create full Product Type file sets for the catalog and admin?
If not, you can remake the product_types table back to its original format and that should fix things ...
PHP Code:
DROP TABLE IF EXISTS product_types;
CREATE TABLE product_types (
type_id int(11) NOT NULL auto_increment,
type_name varchar(255) NOT NULL default '',
type_handler varchar(255) NOT NULL default '',
type_master_type int(11) NOT NULL default '1',
allow_add_to_cart char(1) NOT NULL default 'Y',
default_image varchar(255) NOT NULL default '',
date_added datetime NOT NULL default '0001-01-01 00:00:00',
last_modified datetime NOT NULL default '0001-01-01 00:00:00',
PRIMARY KEY (type_id),
KEY idx_type_master_type_zen (type_master_type)
) TYPE=MyISAM;
PHP Code:
INSERT INTO product_types VALUES (1, 'Product - General', 'product', '1', 'Y', '', now(), now());
INSERT INTO product_types VALUES (2, 'Product - Music', 'product_music', '1', 'Y', '', now(), now());
INSERT INTO product_types VALUES (3, 'Document - General', 'document_general', '3', 'N', '', now(), now());
INSERT INTO product_types VALUES (4, 'Document - Product', 'document_product', '3', 'Y', '', now(), now());
INSERT INTO product_types VALUES (5, 'Product - Free Shipping', 'product_free_shipping', '1', 'Y', '', now(), now());
