Result of search category

Hi,
if I search the word " rasaerba " ( for example ) I can see the products but if I go on the category page is white ... I can not understand why?
I use hika business, the domain is www.fershop.eu .
Using the menu on the category pages are normal ...

Thank you, Enrico.

Hi,

that's because you need to enter the id of your category listing menu item in the "menu" (or "itemid") option of your search plugins.

Perfect!
your help is always very helpful, great service!

Enrico.
