If your news comes out on the storefront side showing html tags:

<p>Bla bla bla</p><p>We are pleased to announce ...

This means the plugin was installed without admin sanitization rules, so when you show it on the storefront, you will have to use something like:

<div class="news-content"><?php echo htmlspecialchars_decode(stripslashes($news_content)); ?></div>

In includes/templates/template_default/templates/tpl_article_default.php instead of just

<div class="news-content"><?= $news_content ?></div>
