Catalogue not displaying

Hi

I’ve previously used this plugin on a site running WordPress 4.3.2 with no issues. I’ve just switched to a new server running 4.7.4 and the catalogue refuses to display at all. I’m using the standard shortcode [product-catalog id=’1′] and have tried variations – catalogue instead of catalog, id=”1″ instead of id=’1′ but still nothing.

Anyone have any ideas??
Thank you
