Category Pagination

Hi!

Subdomains as categories works great but I have a problem with pagination.
It`s not working – a cant change the page to see more posts.

Next thing is that link do pages od categories are example.com/page/2 not subdomain.example.com/page/2(this forma, not working too)

Can you help me? Do I need to change something i plugin/theme code?
