Hi Rodica,
I am not using WooCommerce and the site was working fine until the Zerif Lite Version 1.5.4 update several days ago. It was at that point that the graphic broke. I had already been using the latest version of WordPress Version 4.1.1.
Is there a way to go back to an older version of Zerif Lite to see if that fixes the issue for now?
Thank you,
Joel
