Facebook Share Button Code Not Working

I am using the code directly from Facebook’s share button page (https://developers.facebook.com/docs/plugins/share-button). The only change is that I’m using get_permalink() to pull the post’s url. The problem occurs when I click on the share button. A window opens up for a second and then immediately closes.

//Social share buttons to the blog posts
    function facebookscript() {
    	if (is_single()) {
    	echo '<div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.7&appId=[removed]"; fjs.parentNode.insertBefore(js, fjs); }(document, \'script\', \'facebook-jssdk\'));</script>';
    }
    }

add_action('fl_body_open','facebookscript');

    function posttopsocial() { 

      	$postpermalink = get_permalink();
    	$emailshare = '<a class="email-button" href="mailto:?Subject=Triune Article&Body=Interesting%20Article%20from%20Triune!%20'.$postpermalink.'" target="_blank"><i class="fa fa-envelope-o"></i> Email</a>';

    	//TEMPORARY REMOVED ->

	if (is_single()) {
		echo $facebookscript;
		echo '<div id="posttopsocial"><a href="https://twitter.com/share" class="twitter-share-button" data-count="horizontal" data-via="mwdeterding">Tweet</a><script type="text/javascript" src="https://platform.twitter.com/widgets.js"></script>
			<script src="https://connect.facebook.net/en_US/all.js#appId=[removed]&xfbml=1"></script> <fb:like href="https://triuneleadershipservices.com/build-environment-people-aspire-join/" send="false" layout="button_count" width="90" show_faces="false" font="tahoma"></fb:like>
			<div class="fb-share-button" data-href="'.$permalink.'" data-layout="button_count" data-size="small" data-mobile-iframe="true"><a class="fb-xfbml-parse-ignore" target="_blank" href="https://www.facebook.com/sharer/sharer.php?u='.$permalink.'%2F&src=sdkpreparse">Share</a></div>
			<script src="https://platform.linkedin.com/in.js" type="text/javascript"></script> <script type="IN/Share" data-counter="right"></script>'.$emailshare.'</div><br />';
	}
 }
add_action('fl_post_top_meta_open','posttopsocial');

I also noticed from running inspect that the following error is showing up:

Redirect at origin ‘https://triuneclone.flywheelsites.com’ has been blocked from loading by Cross-Origin Resource Sharing policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘https://triuneleadershipservices.com’ is therefore not allowed access.

I ran a search and replace to remove the temp domain but that didn’t solve it. Any suggestions?
