Layered Navigation Not Showing Products On Parent Category Pages

[jennywill]

Layered Navigation Version 2.1.0

Prestashop Version 1.6.1.0

 

I have the layered navigation module installed and updated to the latest version. I have uninstalled, reinstalled, cleared cache etc.  I have a pretty large product list, and all he products are categorized accordingly. 

 

The problem is that on this version, products are not showing on the category and subcategory pages.  The filters are there but do nothing.  

 

When I get to the lowest category level, then the products pop and the filters work.  But they should work on parent categories. 

 

A Debug note is that if I take a product and put it directly in the parent category, then the filters will work and products will pop on the first filter. But adding a product to every parent category is not optimal and causes other problems.  I also have 300+ categories, so we don't want to do this hack if we don't have to.

 

Another Note that the layered nav modules' indexes and caches are not working either.  The server is set to the highest time out (for dev purpose only) but I get a 1 returned on a white screen when I build attribute index and when I build URL index.  

When I build entire index after about 5 min or so I get the error No data received, ERR_EMPTY_RESPONSE.  

 

Any ideas on where this can be fixed or an older version of the module I can revert to to fix it?  I need this feature to work urgently. Thanks in advance for any ideas.
