AWD Facebook and Page Builder

Yesterday I installed AWD Facebook. I went through and set everything up just the way I wanted it, and then discovered that the Page Builder plugin has an issue with AWD Facebook. With both enabled I lose the ability to fill in the content of a newly create a post, with or without using Page Builder.

This is the error I’m getting:
Fatal error: Class ‘AWD_facebook_widget_likebox’ not found in /home/content/86/10679686/html/users/myshadeofglory/sites/wordpress/wp-content/plugins/siteorigin-panels/tpl/metabox-panels.php on line 9

I’ve found the bit of code this is referencing, but no idea what’s causing the error. I like Page Builder, but if there’s another page designer out there that’s equally powerful and open source I’d be willing to try that to bypass the issue. Any help would be appreciated.
