J-BusinessDirectory - don't working

Hello

Sorry for my english but I'm french.

I installed the component successfully but when I want to edit, delete, or do anything ... I have a blank page or I go back on the list.

I can not use or make any modification to the component

I am under joomla 3.4.3
