title: Can't open or move widgets after Wordpress update
body: <p>I recently updated my WordPress site <code>http://www.yourwhiteknight.com/</code> to 4.1.5 and found that I can't move or open any widgets on the widgets page. If I try to add one, I don't get the menu to add it to a widget and I can't drag and drop on into a sidebar. I can't click the down arrow on any widgets or on any sidebars that are not open in order to edit their contents. </p>
  
  <p>I believe the version I was working with before was 3.5.2. I even tried to go to the customizer but it just gets stuck constantly trying to reload the page, some sort of redirect loop. </p>
  
  <p>Has anyone had this problem before and can point me in the direction of a solution? </p>
  
  <p>I am at a complete loss, other than uploading the older version of wordpress. If I do that, I don't know if the database will still work due to any changes in the DB from the upgrade. I can't revert to the old database because the client has already made a lot of changes.</p>
