I noticed that after the update to 1.3.0 items are marked as sold ( using veronika theme).

Maybe it is just coincidence, maybe it has to do with the plugin. I dont know. Maybe other users will have the same issue.

I will check first what the reason of this behaviour is

plugin cooperates with veronika theme and it's sold status. I need to check if there is not condition for update to check for quantities, but based on your description there is....
