[SOLVED] 'PreserveTimestamp = $false' not working -- PowerShell script

Error: Exception calling "Check" with "0" argument(s): "**Upload of file 'somefile.txt' was successful, but error occurred while setting the permissions and/or timestamp.**

If the problem persists, turn off setting permissions or preserving timestamp. Alternatively you can turn on 'Ignore permission errors' option.
The server does not support the operation.
Error code: 8
