Fatal error: Call-time pass-by-reference – Help?

This just starting occurring:
Fatal error: Call-time pass-by-reference has been removed in /home/icontrol/public_html/custom/remote/plugins/hlt-bootstrapcss-plugin-widgets.php on line 115

So first question I have is why would the path be in the plugin script be set to access /home/icontrol?

find . -type f -exec grep -riH hlt-bootstrapcss-plugin-widgets.php {} \;
Result:
./wp-content/plugins/wordpress-bootstrap-css/views/widgets/bootstrapcss_widgets.php: src=”http://www.icontrolwp.com/custom/remote/plugins/hlt-bootstrapcss-plugin-widgets.php?’.$sSubPageNow.’snippet=’.$insSnippet.'”
