Hi there DW Support.
We are experiencing an error on one of our customer sites, where the search all of a sudden stops working, due to the products page/dw backend, somehow forgets the Navigationtag value set in the backend.
So if i go into the backend, and enters the "properties" page on the products page (Content -> Products -> right click - > "Properties"), and from this page click "Save and close" the search ends up working again.
Otherwise the console just throws an error that the product feed returns html instead of json.
I hope that you guys can help.
