The blank page is because you don't have a external_body.html
file in your style/prosilver/templates
directory.
A very basic external_body.html
will look something like this. Obviously, you'll have to integrate this into your home page's theme.
<!-- BEGIN announcements -->
Title: {announcements.TOPIC_TITLE}<br />
Post author: {announcements.POST_AUTHOR}<br />
Post date: {announcements.POST_DATE}<br />
Last post text: {announcements.POST_TEXT}<br />
Post link: {announcements.POST_LINK}
<!-- END announcements -->
Then, using the file provided by battye of the phpBB.com MOD team, and putting it in the root of your forum, you can show the most recent posts.

If you don't want this in the root of your forum, you need to modify this line to use the appropriate path to point to the root of your forum:
$phpbb_root_path = (defined('PHPBB_ROOT_PATH')) ? PHPBB_ROOT_PATH : './';
The two lines indicating where to change your block of code are the heart of what gets displayed. Above, I've posted Example 4 from your supplied link. Replacing the entire block of code from the other examples will work as well.
Finally, you may need to clear your cache from the ACP when you make template changes.
