Plugin Causes Featured Image Error on WordPress

Hi guys –

I found an error that this plugin is causing.

I found out this week that I could not add a featured image to any post or page in WordPress. Upon clicking “Set Featured Image”, the media library folder would open, and the first image would be a blank grey box, with no attributes at all. The blank image cannot be deleted, nor edited, and when you try to select any other image in the media library as the featured image, the window closes and no featured image will exist on the post or page.

I disabled every plugin on my site (36 of them) and tested each one, and the cause if this plugin. Once this plugin is disabled, the featured image selector works again, and the fake grey image no longer exists. As soon as the plugin is enabled, the image reappears and no featured image can ever again be set on a post or a page.
