commerce auction 出現錯誤
•Notice: Undefined offset: 0 in commerce_auction_node_presave() (line 263 of D:\htdocs\app4trade\sites\all\modules\commerce_auction\commerce_auction.module).
•EntityMalformedException: Missing bundle property on entity of type commerce_product. in entity_extract_ids() (line 7633 of D:\htdocs\app4trade\includes\common.inc).
到底如何修改
有沒有其他拍賣比較容易使用的模組??
