This question may be related to a resolved thread.
The same thing is happening at my site.
If I assign a category, the entry disappears from the home page. If I clear the category, it still does not appear. If I delete and recreate the entry, it will appear again.
{exp:channel:entries channel="news_articles" limit="2" disable="pagination" status="Top Story" }
<h4>{title}</h4>
<p> </p><h5><span class="by">By </span> {author}</h5>
<p> {article_excerpt}<br />
<a href="http://{title_permalink=" class="read_story">Read Story</a><br />
{/exp:channel:entries}I have the latest build installed. Fresh install, not an upgrade.
What could be causing this?
