Hi! SSH SFTP Updater Support is a great plugin but I have a problem uploading zip themes or plugin file using wordpress multisite 3.5.2.
After upload the file worpdress returns this error
"Upload plugin/theme "File is empty. Please upload something more substantial".
The workaround is to upload manually using SFTP connection.
That's not a size limit problem because I have the same problem with very light plugin file.
Thanks for your support
