Cuando vas a la cualquier página que no sea la primera recibes error 404. Afortunadamente puedes solucionar el error puedes pegar el siguiente código en el archivo functions.php de tu theme.
 
function remove_page_from_query_string($query_string)
{
    if ($query_string['name'] == 'page' && isset($query_string['page'])) {
        unset($query_string['name']);
        // 'page' in the query_string looks like '/2', so split it out
        list($delim, $page_index) = split('/', $query_string['page']);
        $query_string['paged'] = $page_index;
    }
    return $query_string;
