Table recently_viewed_product empty

[xcy7e]

Though manually applying your v6.6 changes, the plugin isn't working in v6.6.4.1.

The block in backend works fine, settings are there, from backend perspective, everything looks fine. However browsing the storefront, clicking some products, the block is never shown where it should be, neither its heading, nor any products (but assigned margin values fill up the space - it's there, but empty)ü
