The following plug-in
http://wordpress.org/extend/plugins/wp-table/
doesn’t work in 2.7.1 but you can fix it.
In the wp-table-admin.php file line 165 looks like this:
$csv_file = ABSPATH.get_option(’upload_path’ ).’/’.$_FILES['csv_file']['name']; // set upload path
It needs changed to:
$csv_file = $_FILES['csv_file']['name']; // set upload path
