fix được chưa bro ơi, tôi khóc mất

[vlongle29]

sai chữ ký thật là m.n chạy sai trình duyệt á, mail nào mà m.n nhận được sau khi đăng ký sandbox thì chạy trình duyệt ứng với lại email đó

Mình đổi sang 3 4 trình duyệt khác nhau thì vẫn bị bạn ạ. Mà cái này thì cũng nhiều người ý kiến về sai chữ ký nhiều rồi =)) bê nguyên template trên vnpay + copy tmn_code - vnp_hashsecret từ mail rồi mà vẫn bị sai chữ ký
