Hi.

In category page or search result page, filter for specification attributes does not appear.

Done so far:

-Multiple spec attributes are defined
-Spec attributes added to multiple products (in Spec Attributes tab on Prroduct Edit page)
-Products are linked to same category (in Mappings tab on Product Edit page)
-"Allow Filtering" is checked for all attributes
-Tested both checked and unchecked "Show on product page"
-In mappings, "Is featured product" is not checked.

In CatalogPagingFilteringModel.PrepareSpecsFilters(..) , allFilters is null (e.g, not found in cache). We have not had time to do any further debugging.

Any suggestions?

Hi,
Go to panel administration -> Configuration -> Settings -> Catalog settings -> Performance tab, please uncheck settings "Ignore filtering specifications attribute option (sitewide)"

Regards
Krzysztof

Thanks a lot! Been stuck with this for days, changing this setting was the solution.
