Please help, I have been working on this PO for days, thinking it's saving but it's not. I'm trying to update the quantities, but it's not saving
The second screen shot is after clicking save!!!!
I'm sorry but we can't know what is causing that by looking at a screenshot.
The first thing I would try is to discard any possible conflict with a 3rd party plugin.
Can you try to disable all your plugins except WooCommerce and ATUM and try that way, please?
