I just upgraded from 18.104.22.168 to 22.214.171.124 i was banging my head against a’ SQLSTATE: Integrity constraint violation: 1062 Duplicate error
when i finely solved i understood what causes the problem.
the problem is : that when i use authorize.net as a payment gateway the key base_hidden_tax_invoiced get the value 0.000
i need to understand how can i fix this?
is this something concerning authorize.net? or is it magento related and can be fixed?
