WCFM Vendor’s page

Hello,
I installed and configured your plugin but have a strange issue.
I use WCFM (multi vendor woocommerce plugin) and placed Sassy widget in the Vendor’s Page Sidebar.
If the Vendor has Products, then Sassy widget works (icons displayed and sharing possible).
If the Vendor has NO Product, then Sassy widget DON’T work (no icons displayed, therefore no sharing possible).

I tried to inspect the NOT WORKING page and found this error:
(index):1 Failed to load resource: the server responded with a status of 404 (Not Found)
jquery-migrate.min.js?ver=1.4.1:2 JQMIGRATE: Migrate is installed, version 1.4.1

No error on working pages.
