Here is the code for the blocks:

1. File: wp-content\themes\Newspaper\includes\wp-booster\td_module.php

Add this: https://pastebin.com/KsfC74zm below the author section

2. Locate the block that you want to use (ex: wp-content\themes\Newspaper\includes\modules\td_module_17.php

Replace this:
<?php echo $this->get_author();?>

With this:
<?php echo $this->get_coauthors();?>

You can have featured videos by using this:

1. Install this plugin: Featured Video Plus

2. Customize the plugin settings (width and height, loop, autoplay, etc)

3. Modify the article template file (I have used single_template_6.php for this example)

4. Add this code at the top of the page

$featured_video_plus = new featured_video_plus($post);

(for this example I added the code below this line: $td_mod_single = new td_module_single($post); )

5. Find the code for the featured image: https://pastebin.com/igSnQQA3

6. Replace the image code with this: https://pastebin.com/gUg7ryi9

7. Upload your video on your site and place the link in the plugin section of the article. You don’t need to use the video mode of the post. You can also add featured image to the article but as long as a video is added, the image will not be visible.

8. Customize the aspect of the video using css/js

For some reasons the php code is broken after I publish the post and I cannot edit the post anymore.

The correct code is here:

Plugin used: Co Authors Plus 3.2.2

Multiple authors links below the article title

Modified files: find the file template that you want to use > loop-single.php, loop-single(1, 5, 9, 10).php, single_template_(2, 3, 4, 6, 7, 8, 11, 12, 13).php,

Replace this:

<?php echo $td_mod_single->get_author();?>

With: https://pastebin.com/7Y8kpfTy

CSS:

header .td-post-author-name.multiple-authors a {
margin-right: 0;
}

header .td-post-author-name.multiple-authors .td-author-by {
margin-right: 5px;
}

.td-post-author-name.multiple-authors a:after {
content:”,”;
margin-right: 6px;
}

.td-post-author-name.multiple-authors a:last-of-type:after {
content:””;
margin-right: 3px;
}

Multiple authors boxes on article page

Modified files: find the file template that you want to use > loop-single.php, loop-single(1-13).php

Replace this:

<?php echo $td_mod_single->get_author_box();?>
