I am using a theme called "Zylyz" on this website: http://www.finemeat.co.uk/
You can click on the recipes, and the posts which work fine. However when you click on a category up on the top menu - it takes you to a 404 page which is broken. I am trying to figure out how to get category pages to work.
I am happy to provide any other information required - I don't know what may be pertinent at this time.
