Further more; I just tried to fix the problem by Deleting the Plugin, and reinstalling, but still the problem persists.
I have now fixed the problem. I simply persisted with reloading the page and trying to as quickly as possible click ‘Screen Options’ and uncheck ‘Thumbnails’ until I was quick enough to be successful. The plugin is now working in that the main Stock Manager window in displaying my woocommerce stock.
Whatever you do; DON’T CHECK THUMBNAILS is Screen Options.
