My filter by price navigation shows but when a filter is clicked it just posts back to the same page with no change applied.
The filter categories are distributed evenly in line with the price set for products in the category and the correct number of products in each price range displays properly.

In the admin panel go to Catalog->Attributes->Manage Attributes.
Find the attribute with code 'price'. Select the row.
Then go to Properties->Front end properties.
There is a drop down "
Use In Layered Navigation" and another one "Use In Search Results Layered Navigation". Adjust these two as you like.
