[Grisu74]

Hello everyone I am new to the forum and just use VM, VM since I updated to the latest version, on the home page gives me an error about overwriting on "add to cart", how can I fix it?
Also when I try to cancel an order within VM gives me this error:

VMerror: Seems the used shipmentmethod got deleted
VMerror: TableOrders delete Order shipmentTable __virtuemart_shipment_plg_ = # = `11` virtuemart_order_id dbErrorMsg
VMerror: VirtueMartModelOrders :: remove 11
Order can not be deleted

Help me please?? thank you very much
