I see no checkboxes. How do I fix this?

If you are using Improved Layered Navigation and see no checkboxes, please add the extension's CSS to your styles file (see the installation instructions in your extension package).

Also you need to copy the images from here:

skin/frontend/base/default/* ? skin/frontend/[YOUR PACKAGE]/[YOUR THEME]

See more details on Improved Layered Navigation page
