Hi ,
for some reasons product disappeared in some categories of our website:
http://www.teasoul.net/en/product-category/material/glass/
http://www.teasoul.net/en/product-category/material/bamboo/
http://www.teasoul.net/en/product-category/type-of-accessories/various-accessories/
there is the association in the backend, i can see them if I browse logged in but the normal user see the “no products were found” page
