MarketPress: Order data are lost

All orders on my site are empty. It's very bad as clients pay for products, but I don't have any client's details.
I've performed plugin conflict test, but this doesn't help. I also tried to implement this hotfix, but it doesn't help:

I also found that the issue happens not only with Stripe but with PayPal as well.
