I’m having the same issue, I think. I’m getting several JS console errors when the pro and regular plugins are enabled – the errors disappear when the plugins are disabled. Here’s what I’m getting:
vtwpr-admin-script.js?ver=4.1.1:1015 Uncaught TypeError: Cannot set property ‘value’ of null
load-scripts.php?c=1&load[]=hoverIntent,common,admin-bar,thickbox,plugin-install,svg-painter,heartb…:562 Uncaught TypeError: Cannot read property ‘hasClass’ of undefined
I’m using WordPress 4.1.1.
