Further, you might want to change the Related Posts section title and show the Post Category name instead. You can do this by adding a custom code (filter). 

To do this, you would need to add the following filter to the functions.php file of your Child Theme:

add_filter( 'astra_related_posts_title', 'astra_related_poat_title' );
function astra_related_poat_title() {
   return sprintf(
	'<div class="ast-related-posts-title-section"> <%1$s class="ast-related-posts-title"> %2$s </%1$s> </div>',
	'h2',// enter your custom string here
	esc_html__( get_the_category()[0]->name, 'astra' )
   );
}

Once the filter is added, the Related Posts section title will display the category name of the current post:

If you don’t have your Child Theme installed, please check this article on how to do it.

If you are not sure how to add this code, please check this article. 

You can change these labels with any custom text by adding a custom code (filter). To do this, you would need to add the following filter to the functions.php file of your Child Theme:

add_filter('astra_default_strings' , 'call_back');
 function call_back( $default ){
 $default['string-blog-navigation-previous'] = '<span class="ast-left-arrow">&larr;</span> ' . __( 'Custom Previous Page', 'astra' );
 $default['string-blog-navigation-next'] = __( 'Custom Next Page', 'astra' ) . ' <span class="ast-right-arrow">&rarr;</span>';
 return $default;
 }

This code will rename your navigation links to “Custom Previous Page” and “Custom Next Page”. You can replace these link labels with any other text by modifying the bolded part of the code above.

If you don’t have your Child Theme installed, please check this article on how to do it. Also, If you are not sure how to add this code, please check this article.

If you need to do modify navigational links on your Single Posts, please check out this document.

Types of Issues / Errors for which this document is valid –

1. Class is not found – WP_Image_Editor_Imagick
2. Call to undefined method WP_Image_Editor_Imagick::get_error_message()
3. wp_options table is bloated with entries like this – wp_addon_database_migration_batch_4935ee10bd16fca38a7cb9a9f5904d

In the above cases, there might sometimes be a conflict with the specific servers. For such cases you can disable Image Processing from Astra using the below filter.

You can use the following filter in the child theme’s functions.php –

add_filter( 'astra_image_resizer', '__return_false' );

/*
 * Filters to support meta-structure for CPT Single Posts & Archive
 */

add_filter( 'astra_blog_archive_post_type_meta', 'astra_blog_archive_post_type_meta_func' );

function astra_blog_archive_post_type_meta_func( $post_type_array ) {
    array_push( $post_type_array, 'movies' ); //Here movies is the slug of CPT, you will need to update with the respective slug of your CPT
    return $post_type_array;
}

add_filter( 'astra_single_post_type_meta', 'astra_single_post_type_meta_func' );

function astra_single_post_type_meta_func( $post_type_array ) {
    array_push( $post_type_array, 'movies' ); //Here movies is the slug of CPT, you will need to update with the respective slug of your CPT
    return $post_type_array;
}

Why?

The Featured Images added to each post are set a link to the same post.

How to clear?

From the Astra Theme version – 2.2.2 we providing a filter using which the link to the post can be removed.

Filter: The filter has been added to remove the featured image link on the blog page.

/**
  * Remove HTML before tag for link.
  * @param string $markup markup of post.
  * @return string
  */
function astra_remove_link_before( $markup ) {
    $markup = __return_empty_string();
    return $markup;
}

/**
  * Remove HTML after tag for link.
  * @param string $markup markup of post.
  * @return string
  */
function astra_remove_link_after( $markup ) {
    $markup = __return_empty_string();
    return $markup;
}

add_filter( 'astra_blog_post_featured_image_link_before', 'astra_remove_link_before' );
add_filter( 'astra_blog_post_featured_image_link_after', 'astra_remove_link_after' );

Note: Add the above filter to your child theme’s functions.php, here’s an article to help you Add Custom code.

// Filter to remove featured image link on Archive Page

add_filter( 'astra_blog_post_featured_image_link_before', '__return_empty_string' );
add_filter( 'astra_blog_post_featured_image_link_after', '__return_empty_string' );

Note: Add the above filter to your child theme’s functions.php, here’s an article to help you Add Custom code.

1. Replace default navigation strings with next/previous post titles

The following filter will fetch the Previous and Next post title and will display them as navigation links.

add_filter( 'astra_single_post_navigation', 'astra_change_next_prev_text' );

/**
 * Function to change the Next Post/ Previous post text.
 *
 * @param array $args Arguments for next post / previous post links.
 * @return array
 */
function astra_change_next_prev_text( $args ) {
	$next_post = get_next_post();
	$prev_post = get_previous_post();
	$next_text = false;
	if ( $next_post ) {
		$next_text = sprintf(
			'%s <span class="ast-right-arrow">→</span>',
			$next_post->post_title
		);
	}
	$prev_text = false;
	if ( $prev_post ) {
		$prev_text = sprintf(
			'<span class="ast-left-arrow">←</span> %s',
			$prev_post->post_title
		);
	}
	$args['next_text'] = $next_text;
	$args['prev_text'] = $prev_text;
	return $args;
}

2. Replace default navigation strings with custom text

The following filter will replace Previous and Next links with your custom text. You can replace your text with – ‘My Previous Custom Text’ and ‘My Next Custom Text’ in the following filter code.

add_filter( 'astra_single_post_navigation', 'astra_change_next_prev_text' );
 
/**
 * Function to change the Next Post/ Previous post text.
 *
 * @param array $args Arguments for next post / previous post links.
 * @return array
 */
function astra_change_next_prev_text( $args ) {
    $next_post = get_next_post();
    $prev_post = get_previous_post();
    $next_text = false;
    if ( $next_post ) {
        $next_text = sprintf(
            '%s <span class="ast-right-arrow">→</span>',
            'My Next Custom Text'
        );
    }
    $prev_text = false;
    if ( $prev_post ) {
        $prev_text = sprintf(
            '<span class="ast-left-arrow">←</span> %s',
            'My Previous Custom Text'
        );
    }
    $args['next_text'] = $next_text;
    $args['prev_text'] = $prev_text;
    return $args;
}

Note: Add the above code in the child theme’s functions.php file.

Published date is displayed in the front end

Both, published as well as updated dates are available in the markup.

If you want to display last updated date for the post to your visitors, use the following custom code –

/**
 * Display only last modified date in the post metadata.
 *
 * @param String $output Markup for the last modified date.
 * @return void
 */
function your_prefix_post_date( $output ) {
	$output        = '';
	$format        = apply_filters( 'astra_post_date_format', '' );
	$modified_date = esc_html( get_the_modified_date( $format ) );
	$modified_on   = sprintf(
		esc_html( '%s' ),
		$modified_date
	);
	$output       .= '';
	$output       .= ' ' . $modified_on . '';
	$output       .= '';
	return $output;
}
add_filter( 'astra_post_date', 'your_prefix_post_date' );

It hides the published date and makes updated date visible.
