Hello Butler, As I suspected, this theme is missing many required templates. Also it is overriding all WP template system. Why reinvent the wheel? WordPress has the best template system and this theme is trying to override all. Apart for this there are many errors and warnings in this theme. I will suggest you to choose a different theme or you can ask developer about fixing this issue. Lemme know if they have any question regarding category page template. Cheers.

AnsPress question and answers are just normal WordPress post. There are lots of plugin available for backup and migration use one of them. I will recommend updraft backup.
