I should add that the carousel displays 2 posts at a time, each in it’s own div. You can see this in the example code I give.
Therefore, I need the loop to work with this type of structure:
<ul>
<li>
<div>Post 1</div>
<div>Post 2</div>
</li>
<li>
<div>Post 3</div>
<div>Post 4</div>
</li>
<li>
<div>Post 5</div>
<div>Post 6</div>
</li>
</ul>
Thanks everyone!
Does each site share the same server? Server settings?
Perhaps your server settings, .htaccess files, or some other file is changing the way the theme interacts with one site.
