running erp7 on a synology nas. somehow the supplier and customer kanban AND list view give this error. I can create suppliers and customers via a purchase or sales order. they just don't show up in my default views. any thoughts? Kanban view works fine for products.

quote ERROR:

View error

Can't find field 'display_name' in the following view parts composing the view of object model 'res.partner': * res.partner kanban

Either you wrongly customized this view, or some modules bringing those views are not compatible with your current data model
