Nothing is being exported out with registrants

I am using Event Booking Version 1.4.3 and nothing is being exported into the CSV file when trying to export registrants. I have already provided back end information in a previous support ticket. If you need it again I will provide it. Thanks for your help in advance.

Hi

Please submit a support ticket giving me administrator and FTP account of your site so that I can check it for you .

Regards,
