Hi this is my first post hope this is ok. I am having a issue with topics. i believe i have it all set up correctly. when ever i try and use the popular topics block all i get is page not found. /news/topic/6/%20company%20news.

I have my attributes set up to the correct categories.
when i edit the topic list block i have the mode, topic tree and results page all set up.

Am i missing some thing as i cannot figure this out. Any help would be great
