remove WordPress SEO columns from admin post tables

wordpress-remove-seo-columns.php

<?php

function rkv_remove_columns( $columns ) {

	// remove the Yoast SEO columns
	unset( $columns['wpseo-score'] );
	unset( $columns['wpseo-title'] );
	unset( $columns['wpseo-metadesc'] );
	unset( $columns['wpseo-focuskw'] );

	return $columns;

}
add_filter ( 'manage_edit-post_columns', 'rkv_remove_columns' );

Thank you

And the latest addition:
unset( $columns['wpseo-links'] );

unset all those columns for Download manager plugin (https://www.wpdownloadmanager.com/):

//unset all those WPSEO shizzle  columns
function rkv_remove_columns( $columns ) {
	unset( $columns['wpseo-score-readability'] );
	unset( $columns['wpseo-score'] );
	unset( $columns['wpseo-title'] );
	unset( $columns['wpseo-metadesc'] );
	unset( $columns['wpseo-focuskw'] );
	return $columns;
}
add_filter ( 'manage_edit-wpdmpro_columns', 'rkv_remove_columns' );

unset( $columns['wpseo-links'] ); can be added as well.

works great, but I search some similar functionality.
Hidden all languages and display only one column with flag instead "check", because now I have 11 languages = 11 columns

I resolve my problem by remove all columns with languages and I add custom column with current lang.

Maybe can help someone:

function polylang_extra_columns_head($defaults) {
	$defaults['lang'] = 'Lang';
	return $defaults;
}

function polylang_extra_columns_content($column_name, $post_ID) {
	if ($column_name == 'lang') {
		echo strtoupper( pll_get_post_language($post_ID) );
	}
}

add_filter('manage_posts_columns', 'polylang_extra_columns_head');
add_action('manage_posts_custom_column', 'polylang_extra_columns_content', 10, 2);
