Batch upload not working

It seems that batch upload of zip files are not working.

Does not seem to be due to zip file itself.

This is the PHP error:

Warning: ZipArchive::open(): Empty string as source in /var/www/fellesmenighetsblad.no/public_html/site/wp-content/plugins/memphis-documents-library/mdocs-import.php on line 232

The reason for this is this call:

$zip_result = mdocs_unzip($_FILES[‘mdocs-batch’][‘tmp_name’], ‘/tmp’);

It seems that $_FILES[‘mdocs-batch’][‘tmp_name’] has no value.
