Workaround for Multi-Warehouse Extension

To make the two extensions compatible: 

1. Open the following file: app/code/local/Innoexts/Warehouse/etc/config.xml 

2. Edit the file to remove the following lines:

<order_pdf_invoice>Innoexts_Warehouse_Model_Sales_Order_Pdf_Invoice</order_pdf_invoice>
 
<order_pdf_items_invoice_default>Innoexts_Warehouse_Model_Sales_Order_Pdf_Items_Invoice_Default</order_pdf_items_invoice_default>
 
<order_pdf_creditmemo>Innoexts_Warehouse_Model_Sales_Order_Pdf_Creditmemo</order_pdf_creditmemo>
 
<order_pdf_items_creditmemo_default>Innoexts_Warehouse_Model_Sales_Order_Pdf_Items_Creditmemo_Default</order_pdf_items_creditmemo_default>
 
<order_pdf_shipment>Innoexts_Warehouse_Model_Sales_Order_Pdf_Shipment</order_pdf_shipment>
 
<order_pdf_items_shipment_default>Innoexts_Warehouse_Model_Sales_Order_Pdf_Items_Shipment_Default</order_pdf_items_shipment_default>

3. Once saved, refresh your cache to allow the Pdf Customiser pdfs to take precedence.
