ES Content Plugin throws error when trying to delete Joomla article from trash

When I tried to 'Empty Trash' on my standard Joomla articles, I get...

Fatal error: Class 'FD' not found in /public_html/plugins/content/easysocial/easysocial.php on line 453

I was able to get around it by just temporarily disabling the plugin, and then emptying trash... but just reporting in case this is a general issue that can be fixed.

I'm on latest Joomla and latest EasySocial versions.
