I used to be able to add items to a bundle. Since today I can no longer do so.
The dashboard shows no items:
And When I try to do it by code by calling SetCatalogItems, I get this error message:
Unknown item 'item_id' in bundle contents of item 'bundle_id'.
UPDATE:
I was able to add bundle with items by calling UpdateCatalogItems. The dashboard is still broken, though.
