Read more option not appearing in translated posts

yes I am using version 1.3.27. And I had removed previously filter in function.php. So you mean now it should work without adding filter in function.php and in plugin? no need to add any filter? Then why is it not working in my site?

Or I need to put the filter somewhere?

Regarding my site translation most if the page was translated earlier too but default was in Nepali and now it is in English language with this plugin.

hi is this the correct code you gave me yesterday?

$content = apply_filters( ‘falang_translate_post_content’, $content );

Or I need to put the old code you provided me previously weeks ago?

old code is

function falang_translate_post_content($content){
    if ( preg_match( '/<!--more(.*?)?-->/', $content, $matches ) ) {
        if ( has_block( 'more', $content ) ) {
            // Remove the core/more block delimiters. They will be left over after $content is split up.
            $content = preg_replace( '/<!-- \/?wp:more(.*?) -->/', '', $content );
        }

        $_post = get_post();

        $output     = '';

        $content = explode( $matches[0], $content, 2 );

        if ( ! empty( $matches[1] ) ) {
            $more_link_text = strip_tags( wp_kses_no_null( trim( $matches[1] ) ) );
        }

        $output = $content[0];

        if ( count( $content ) > 1 ) {
            if ( ! empty( $more_link_text ) ) {
                $output .= apply_filters( 'the_content_more_link', ' <a href="' . get_permalink( $_post ) . "#more-{$_post->ID}\" class=\"more-link\">$more_link_text</a>", $more_link_text );
            }
        }
        $output = force_balance_tags( $output );
        return $output;

    }
    return $content;
}

add_filter('falang_translate_post_content','falang_translate_post_content');

With new code, nothing happens but with old code, full posts are not appearing on the home page, but readers will misunderstand it as full posts because read more .text does not appear in the page break area. It looks like short and incomplete posts It looks like the end of the post.

Please let me know which code should I use. I use both code one after another and both code together too, But still cant see Read more option.

Here is how it look in the original and translated one. link to images
