Many Thanks for your reply.

I get this error, when I add the above code to the child’s theme functions.php: There has been a critical error on your website.

Below is how my functions.php file looks like without the above code:

<?php
add_action( 'wp_enqueue_scripts', 'enqueue_parent_styles' );

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

add_filter( 'get_the_archive_title', function ($title) {    
    if ( is_category() ) {    
            $title = single_cat_title( '', false );    
        } elseif ( is_tag() ) {    
            $title = single_tag_title( '', false );    
        } elseif ( is_author() ) {    
            $title = '<span class="vcard">' . get_the_author() . '</span>' ;    
        } elseif ( is_tax() ) { //for custom post types
            $title = sprintf( __( '%1$s' ), single_term_title( '', false ) );
        }    
    return $title;    
});

Hello,

I did remove the code you mentioned above from the functions.php. It removes Author image.

Also since the new theme update, the child theme breaks posts and pages look:

The heading has been aligned to the left.
The Featured image is not in the middle.
Posts/Pages text has moved to right.

Did you introduce any new stylesheets ?

Thanks
