Can't copy files from a remote server [scp: illegal option]

I can login and view the file list, but can't upload files. My remote server does not seem to accept some of the options for scp set by WinSCP. How to solve this problem ? Thanks in advance !

Here is the error message.

> echo "WinSCP: this is begin-of-file" ; scp -r -1 -d -t "/home/myself/myfile" ; echo "WinSCP: this is end-of-file:$?"
! scp: illegal option -- 1
< WinSCP: this is begin-of-file
! usage: scp [-pqrvBC46] [-F config] [-S program] [-P port]
! [-c cipher] [-i identity] [-o option]
! [[user@]host1:]file1 [...] [[user@]host2:]file2
< inSCP: this is end-of-file:1

I mean "Can't copy file TO a remote server", not FROM.

You have probably turned on "Use scp2 with scp1 compatibility." option of Shell tab of login dialog.

No. I don't. The turned on options of Shell tab are "Lookup user groups", "Clear aliases", "Ignore LS warnings", and "Clear national variables". That's it.
