404 error on category pages

Hi, just tested deploying on Bunny (manually uploaded zip), and I am getting 404 on category pages:

https://tiramisu.b-cdn.net/
https://tiramisu.b-cdn.net/category/drawing-tutorials/

I can see that from all categories, only 2 are working.

How can I fix that?

By the way, is Bunny add-on available to download somewhere?

Thanks!
