Hi

This is a brillant plugin - many thanks.

Summary: In my implementation the plugin only returns products with 32 or less products_attributes records.

Is this just me or has anyone else come across it? I've searched similar postings on this thread but not found any, so my apologies if this has already been covered and solved before.

Symptoms: go to a category and then 'narrow your results', say by selecting a colour. The result that comes back includes all matching products EXCEPT for those with more than 32 products_attributes.

Solving the problem: I deleted a few of the product_attributes from one of the products affected, taking the number down to 27, and it worked. That product now appears in the 'refine your results' page.

How I investigated: I spent three days, on and off, checking everything I could think of including the code, walking through the generated SQL, our data, and removing then re-installing the code, and couldn't find anything. Then I realised that this only happened to products with a large number of product_attributes.

Could it be a configuration issue? I couldn't see a maximum products_attributes variable but there may be one.

Any ideas welcome?

BTW (since some people may ask) we do need more than 32 variants for some of the products.
