Hello,
Have you tried disabling other plugins and reverting to the twentyfourteen theme and seeing if that resolves the issue?
Any alternative go that? Mine is a live site.
I would lose all my widgets and settings if I do so am I right?
Thanks!
Two alternatives:
1.) Create a copy of your site that isn’t live, and try to debug the problem on that copy. You can try setting up another WordPress on your provider and using a migration plugin (like wp-clone or duplicator). You can also try WP Stage Coach. It will let you set up a staging site for free. It’s currently in alpha, so they ask for help testing it and finding bugs.

2.) You can use the javascript console and developer tools in your browser to try and find any scripting errors that are happening and/or look for duplicate js/css files. Are there multiple copies of jquery-ui-[any version here].js loading? Etc.
