Upload errors

I am getting the following error when I attempt to upload a file using webftp.dreamhost.com. This was not a problem until this program upgrade. Anyone have any thoughts or suggestions? This happens regardless of file size. I tried even a 10kb file, which failed.

Could not generate a temporary file.

The error occured in file /usr/local/ndn/web/webftp/includes/filesystem.inc.php on line 1734.

  • function acceptFiles (/usr/local/ndn/web/webftp/modules/upload/upload.inc.php on line 239)
    o argument 0: Array
  • function net2ftp_module_printBody (/usr/local/ndn/web/webftp/main.inc.php on line 321)
  • function net2ftp (/usr/local/ndn/web/webftp/index.php on line 58)
    o argument 0: printBody

I am getting the same error.
