The primary reason this would occur is if there is a fatal javascript error. The source of the error would very likely be the theme or another plugin. You can view the javascript errors by loading the page in Chrome, hitting the F12 key and then clicking the Console tab.

The file name, and/or file path of the the file causing the error just about always indicates the source of the error.

Without a link to the page with the issue the is the best answer I can give you. If you share the link to the page, I’ll take a look.
