Hi Salim,

A lock icon next to an article title is indicating that the article is set to only be visible for agent and admins in the article settings. If this is not the case, the icon is most likely placed in a wrong place on the home page:

{{#if promoted_articles}}
      <section class="articles">
        <h2>{{t 'promoted_articles'}}</h2>
        <ul class="article-list promoted-articles">
          {{#each promoted_articles}}
            <li class="promoted-articles-item">
                <a href="{{url}}">
                  {{title}}

                  {{#if internal}}
                    <svg xmlns="http://www.w3.org/2000/svg" width="16" height="16" focusable="false" viewBox="0 0 16 16" class="icon-lock" title="{{t 'internal'}}">
                      <rect width="12" height="9" x="2" y="7" fill="currentColor" rx="1" ry="1"/>
                      <path fill="none" stroke="currentColor" d="M4.5 7.5V4a3.5 3.5 0 017 0v3.5"/>
                    </svg>
                  {{/if}}
                </a>
            </li>
          {{/each}}
        </ul>
      </section>
    {{/if}}

As you see here (the thing in bold), the icon should be wrapped in an if internal statement in order for it to only show if the article is internal (visible to only agent and admins).

I hope this helps :)
