I am running WP 4.2.2 and plugin V 2.3.2. I cannot get the plugin to work. I have tried both csv and xls formats. I have checked the header box, I have removed the header from the spreadsheet and tried that way. It displays the file and I get a notification saying "Items added to queue." but there is nothing in the queue. I have copy and pasted directly from your samples within the admin and those don't work as well. Says "Log file is empty". Please advise.
