Some links in admin not working correctly
I finally got an error message to work with (TypeError: this.jqObject.data(...) is undefined), which led me to this solution:  https://drupal.org/comment/8677587#comment-8677587:

Hi guys, I am pretty new to Drupal and programming in general, so pleas bear with me... I got the data selector working by configuring the jQuery_update module:
Default JQuery Version: 1.7
Alternate JQuery Version: 1.7
JQuery Compression Level: Development (I doubt this should make any differences)
JQuery and JQuery UI CDN : JQuery
