Yo dudes, let's get the con started with this classic! Haven't seen this beast in a while.

  1. recently updated to 4.6.16
  2. theme Seven
  3. ran update.php after upgrade
  4. cleared Civi and Drupal cache
  5. Drupal cache off

Still the issue with field selects and jQuery error is happening (attached images). Feeling kind of duncey here. Any ideas?

What happens if you change themes to one of the basics? This looks somewhat similar in end result to the Backbone errors that are occurring with some of the themes. Do you see errors on the Manage Events -> Online Registration page also?

  • The "jQuery is undefined" is on all pages of CiviCRM. It doesn't have the negative effect on Online Registration page that it does on New Mailing, however. – CiviTeacher Jun 2 '16 at 15:47

Hmm--in theory Drupal jQuery Update shouldn't make a difference. Ye olde jQuery in Drupal is the reason CiviCRM has its own CRM.$ or cj instead of regular $ or jQuery.

Something must be using the wrong one. If I had to guess, I'd say that some code isn't within a closure.

Installing jQuery Update module fixed the issue. The site was running a 'stock' Drupal 7.43 with no modules except Views, cTools and Webform.
