ติดตั้งในapp เซิฟได้ แต่พอติดตั้งผ่าน ftp ลงเซิฟ ไม่ได้ เป้นเพราะอะไรครับ The directory sites/default/files does not exist. An automated attempt to create this directory failed, possibly due to a permissions problem. To proceed with the installation, either create the directory and modify its permissions manually, or ensure that the installer has the permissions to create it automatically. For more information, please see INSTALL.txt or the on-line handbook.
