Viper Video causing page to be blank

For some reason Viper Video Quicktags is causing a page that I just updated to come out blank. I disabled all the plugins and tested each to discover that Viper Video was causing the problem. It is currently disabled. Also, my widgets will not drag into the sidebar. My client needs to get this blog working asap. https://heartoflivingvibrantly.com/press-room/ She is using 3.1.2 and Ataulupa Atahualpa 3.4.6. Should I use a previous version of Viper Video Quicktags and where can I get it?
