It doesn't seem to have saved and posted my reply, so I'm trying this again...
I am having the exact same issue as the original poster. I followed all of your instructions. None of the customers/items/accounts that are inactive are being used on these invoices. We have literally not made a single customer/item/account inactive in several months (if not years), and this problem just started late last week.
I personally think it's related to this awful invoice revamp/update that QBO did, but either way, I have to be able to create invoices. This service is far too expensive to not be able to do something as simple as creating and saving an invoice. I need this fixed and working today. Please let me know what I can do to fix it, since checking all of the things you suggested did not help.
Thank you.
