Wordpress pagination 404 error "/page/2" - what to do?

The problem mainly arises because permalinks set to Custom Structure /%category%/%postname%/. I understand WordPress assumes "page" is a post from the category.

That is totally normal behaviour. If you want to remove category base you will need to write some custom rewrite rules, not simple rules I must say.

Configure category base to . (dot), put this code in the functions.php of your theme, or better in a plugin, and flush the rewrite rules (code from this post in Daily Web Kit):

add_filter( 'category_rewrite_rules', 'vipx_filter_category_rewrite_rules' );
function vipx_filter_category_rewrite_rules( $rules ) {
    $categories = get_categories( array( 'hide_empty' => false ) );

    if ( is_array( $categories ) && ! empty( $categories ) ) {
        $slugs = array();
        foreach ( $categories as $category ) {
            if ( is_object( $category ) && ! is_wp_error( $category ) ) {
                if ( 0 == $category->category_parent ) {
                    $slugs[] = $category->slug;
                } else {
                    $slugs[] = trim( get_category_parents( $category->term_id, false, '/', true ), '/' );
                }
            }
        }

        if ( ! empty( $slugs ) ) {
            $rules = array();

            foreach ( $slugs as $slug ) {
                $rules[ '(' . $slug . ')/feed/(feed|rdf|rss|rss2|atom)?/?$' ] = 'index.php?category_name=$matches[1]&feed=$matches[2]';
                $rules[ '(' . $slug . ')/(feed|rdf|rss|rss2|atom)/?$' ] = 'index.php?category_name=$matches[1]&feed=$matches[2]';
                $rules[ '(' . $slug . ')(/page/(\d)+/?)?$' ] = 'index.php?category_name=$matches[1]&paged=$matches[3]';
            }
        }
    }
    return $rules;
}

Wordpress - Create a Child Theme

How to Create a Child Theme

1. Create the child theme directory, which will be placed in wp-content/themes folder. The name of your child theme directory is appended with '-child'. You will also want to make sure that there are no spaces in your child theme directory name, which may result in errors.

2. The next step is to create your child theme's stylesheet (style.css). The stylesheet must begin with the following

Theme Name: Twenty Fifteen Child Theme

URI: http://example.com/twenty-fifteen-child/

Description: Twenty Fifteen Child Theme

Author: John Doe

Author URI: http://example.com

Template: twentyfifteen

Version: 1.0.0

License: GNU General Public License v2 or later

License URI: http://www.gnu.org/licenses/gpl-2.0.html

Tags: light, dark, two-columns, right-sidebar, responsive-layout, accessibility-ready Text Domain: twenty-fifteen-child

Note – Template “twentyfifteen” should be same as parent folder name. this is case sensitive. Otherwise you will get the error “the parent theme is missing. please install the x parent theme”

3. Create a functions.php in your child theme directory. The first line of your child theme's functions.php will be an opening PHP tag (), after which you can enqueue your parent and child theme stylesheets.

add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );

function my_theme_enqueue_styles() { wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );

}

where parent-style In your child code, replace the instance of 'parent-style' with 'twentyfifteen-style', like so:

parent_style = 'twentyfifteen-style';
