I'm using the test version of the plugin on my site, I am using License key: baf8a5ad99b188ee599512346d9dea19

It's loaded and activated but I'm getting this error when I go to the Products tab:

Warning: Invalid argument supplied for foreach() in /home/normansp/public_html/wp-content/plugins/web-to-print-online-designer/views/manager-product.php on line 14

Do you have any tips on how to get this working? Thanks kindly!
