Can NOT delete files on NAS White led 1.5TB - TWONKY Problem

WDsupport is doing an awesome job! 5 days passed and they havn’t responded to my request.

The next problem that occured: I cant acces my Drive settings anymore. I recieve this error message:

My Book World Edition - MyBookWorldWarning: Unknown(): open(/tmp/sess_61a9664015e720f1567195841504e7c9, O_RDWR) failed: Read-only file system (30) in Unknown on line 0 Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0

No acces over ftp, http or wd discovery? WTF!!!

This drive is the worst drive I ever connected to my network!
