In admin page, I turned on the mode Manage Stock to Yes. After reindex, when I go to product list page, it got an error like this:
I go to var/log to check what happened, and saw this line:
Can't check requested quantity for products without Source Items support
After search many post in here, I have to temporary fix by delete record in table ui_bookmarks. But it just for a moment, it will be error again later.
How I can fix this?
