Hi: what I do wrong? I mean, I installed the plugin and I have sometimes run it, of course not all the times all the books I selected collect data, but sometimes the plugin show me this message:
As you see in the capture, all the columns that the plugin need are created, so, why the message says "must exist" if those columns really exist?
Regards from Lima, Perú
Blessings
PD
Sorry my grammar
