Check Settings → Permalinks again, if you select default in common settings, all of the pages including categories will be use ?cat={category_name}. To benefit SEO techniques, the best options are post name and custom structure.
If you are using category name in permalink for a post, it’s not a good practice, especially, if you have two or more categories per post. Solutions: Use canonical link tag for the post and add it to your prefered absolute URL. Google will rank only this one and it won’t be as duplicate content.
Check that your category.php file has no errors first. Go to Settings -> Permalinks and save it again to rebuild your permalink structure just in case.

There is no date-based archive for a category. The /category/[slug]/ pages are already “archives”, in that they display old posts over different pages. The different pages can be accessed by adding page/2/, page/3/, … to the URL. The template tags to add these links are next_posts_link() and previous_posts_link(). If you want to add a date-based … Read more
