Error 500 with "No Payment methods available for your country"

[tuananhngd]

Dear sir/madam,

Previous version 1.7.3.2 worked in normal with our configuration. The payment methods is blank but no error

We just upgrade from 1.7.3.2 to 1.7.5.1. We tested and had ERROR 500 at the end of Checkout progress

We check BO and see Payment warning: "It seems there are no recommended payment solutions for your country"

We checked Payment Preferences, it seems no change from old version. All configuration are the samej and config for my country

Please see Images

 

Do you know how to fix it? Help us!

Best regards,
