I have solved the problem resaving my permalink settings.

Thank you!

Can anyone answer me???

Nothing happen!
Indeed does not change pratically the page, except the url

Doesn’t Work, it tell me that i call a undefined function..

If it can help you to help me, this is the code of aviators_pagination()

function aviators_pagination() {
    if( is_singular() ) {
        return;
    }

    global $wp_query;

    /** Stop execution if there's only 1 page */
    if( $wp_query->max_num_pages <= 1 ){
        return;
}

    $paged = ( get_query_var( 'paged' )) ? get_query_var( 'paged' ) : 1;
    //$wp_query = new WP_Query();
    $max   = intval( $wp_query->max_num_pages );

    /** Add current page to the array */
    if ( $paged >= 1 )
        $links[] = $paged;

    /** Add the pages around the current page to the array */
    if ( $paged >= 3 ) {
        $links[] = $paged - 1;
        $links[] = $paged - 2;
    }

    if ( ( $paged + 2 ) <= $wp_query->max_num_pages ) {
        $links[] = $paged + 2;
        $links[] = $paged + 1;
    }

    echo '<div class="clearfix"><div class="center"><ul class="pagination">' . "";

    /** Previous Post Link */
    if ( get_previous_posts_link() ) {
        printf( '<li class="previous">%s</li>', get_previous_posts_link( '<i class="fa fa-angle-left"></i>' ) );
    }

    /** Link to first page, plus ellipses if necessary */
    if ( ! in_array( 1, $links ) ) {
        $class = 1 == $paged ? ' class="active"' : '';

        printf( '<li%s><a href="%s">%s</a></li>' . "", $class, esc_url( get_pagenum_link( 1 ) ), '1' );

        if ( ! in_array( 2, $links ) ) {
            echo '<li class="disabled"><a>...</a></li>';
        }
    }

    /** Link to current page, plus 2 pages in either direction if necessary */
    sort( $links );
    foreach ( (array) $links as $link ) {
        $class = $paged == $link ? ' class="active"' : '';
        printf( '<li%s><a href="%s">%s</a></li>' . "", $class, esc_url( get_pagenum_link( $link ) ), $link );
    }

    /** Link to last page, plus ellipses if necessary */
    if ( ! in_array( $max, $links ) ) {
        if ( ! in_array( $max - 1 , $links ) ) {
            echo '<li><a>...</a></li>' . "";
        }

        $class = $paged == $max ? ' class="active"' : '';
        printf( '<li%s><a href="%s">%s</a></li>' . "", $class, esc_url( get_pagenum_link( $max ) ), $max );
    }

    /** Next Post Link */
    if ( get_next_posts_link() ) {
        printf( '<li class="next">%s</li>', get_next_posts_link( '<i class="fa fa-angle-right"></i>' ) );
    }

    echo '</ul></div></div>' . "";
