I tried to deactivate all plugins and after deactivating one of them i managed to finish order but orded did not containt ordered product. I just got customer info without product info.

Debug.log wasn't helpfull because it showed me only the warning about that one plugin. Also, WooCommerce Status seems fine.

I'm trying to fix this without any succes for 10 hours now and I could really use some fresh ideas, so please help.

Thanks in advance.

In case someone have the same issue:

Problem was in mySQL database, with primary keys.

After importing database from backup everything works fine.
