Widgets appearing on site, BUT are unmanageable in Backend

I don’t know when this happened, perhaps after the latest WP update of 3.8.2 which was done automatically. I hope with this code: define( ‘WP_AUTO_UPDATE_CORE’, false ); that I’ve added to my wp-config.php file, I have stopped this automation, the nerve of WP just doing that to us unexpectedly, sheesh…

Anyway, I would like to manage my widgets, but there is absolutely nothing to manage, see this screen: https://www.jessicavoiceover.com/img/widgetsphp.png

I’ve tried to find a similar thread on this subject, but cannot. I’ve disabled/re-enabled my ‘Display Widgets’ plugin, but nothing changed. I didn’t think that was the problem anyway…

I’m not a developer, so I need layman termed support here… Please help me, I don’t know how to troubleshoot this one and I really need to be able to manage my widgets…

Thanks
