Filters not showing

I added a bunch of products with specification attributes for testing - the filters displayed nicely on the catalog page.

Then I deleted the test products and added the correct one (with new specification attributes) - but now the filters are not displaying. I can't find what I have missed....please assist me.

Hi,

Could you raise a ticket and provide us with admin credentials so we could check your settings ? 

Hi,
After sleeping on the issue I found that I'd ticked "Featured product" - so of course the filters didn't show! After unchecking everything are as desired :-)
