URL not working: class ‘ccfic-source’ code error

On this post the source text is displaying OK but the URL is not working.

If you look at the source on the page the HTML is being rendered as this:

<div class="ccfic">
	<a href="https://dev.henleyherald.com/wp-content/uploads/2016/08/invesco-lakes-challenge-team3.jpg" title="Landscape Test" class="lightbox-added">
	        <span class="ccfic-text">This is a Caption</span> 
		<span class="ccfic-source"></span>
    </a>
	<a href="https://www.neomartek.com/" target="_blank">Source: John Smith</a>
</div>

whereas on your GitHub page is says it should be this:

<div class="ccfic">
    <span class="ccfic-text">This is a Caption</span>
    <span class="ccfic-source"><a href="https://www.neomartek.com/">Source: John Smith</a></span>
</div>

Can you advise why it’s not working?
