OK- went in and created a simplified version- is it working correctly here? It looks like it is.
So- took a look at the webpage and understood what you meant about filtering. You’re creating category url titles manually- and it wasn’t filtering because you didn’t have ‘Use Category URL Titles In Links?’ turned on. If you’re using the url titles in your links? That needs to be ‘on’ in ‘Admin- Weblog Admin- Weblog Management- Global Weblog Prefs’. I’m not entirely sure if/how it would have been working before.
This does mean that if you were autogenerating category id links- i.e. Cx- flipping to ‘Category urls titles’ will now generate those links with a category/cat_url_title. But you need that setting if you’re going to use cat url titles.
Make sense? And does it seem to be working now?
