Tôi vào Plesk để backup database thì báo lỗi:
[COLOR="#FF0000"]The operation you were performing failed. You can retry the operation with or without changing its parameters. You may also want to report this problem to our support so that we could help you as soon as possible[/COLOR]
Kể cả login bằng user Admin và user Client (Cả trên server và trên máy Client). Mong mọi người giúp đỡ
