EDIT: Fix for showing all 0 qty on update to 1.9.39.2 - go to SETTINGS, TOOLS, CLEAR TRANSIENTS solved it for me.
Still showing all 0's on 1.9.39.2
When something is sold after the update, it is added to the column but the last 29 days are gone. How do we get that back?
On a second site I run, we never did the update to the corrupted version but we did the new update and that site still shows all sales for the last 30 days.
