Hi,

i visited your website and tried what you suggested.

You should know that the URL doesn't change/reload when you click a single position. Indeed position details are loaded over AJAX and the URL gets an extra parameter appended all managed by javascript.

The plugin to share works in PHP server side so you need to notify it in some way on the client side and using javascript that the URL is changed after the AJAX request has loaded details for the clicked position.
You have to develop a client side integration.

kind regards
John
