I tried to edit a file in hosting server with winscp, Permission denied. Error code: 3 Error message

1)
I tried to edit a file in hosting server with winscp the file property is 0644

I got error message: Cannot overwite the remote file, press 'Delete' to delete the file and create new one instead of overwriteing it.
Permission denied.
Error code: 3
Error message from server: Permission denied
2) so I tried to delete that file,

I still got Permission denied.

3) I tried to set 0777 for that file
I still got Permission denied.
4) I tried to set permission for its parent older from 0755 to 0777
I still got Permission denied.

I have no idea how to edit that file, is there any experts can help me through.

Best Regards

user

Did you get "Permission denied", when changing the permissions? Or when trying to overwrite the file after you successfully changed the permissions?
