I upgraded and now if I click on a category down the right instead of going to:
domain.ext/category/news/ and displaying a summary of posts, with "read more" to go to the actual page, they are all now displaying:
Sorry, but you are looking for something that isn't here.
The pages are still there, it's just the categories which aren't working. Anybody have an idea how to fix this?
Will deleting the category and then creating it again work, or will that just rename it: category-2/
