  issues.civicrm.org is down right now - but I see this issue: [CRM-12570](http://java-prod.civicrm.osuosl.org:9080/jira/browse/CRM-12570) "Javascript error when mootools is loaded in Joomla backend". I'll also note that everyone reporting this problem is using Joomla. So my guess is that there's a Joomla plugin that's causing a jQuery conflict or similar.
  
  To troubleshoot this, I would:
  
  * Disable all your other Joomla plugins. I hope you're doing your upgrade on a dev server before doing it on a live server! If disabling all of them solves the problem, start turning them back on until you can identify which one has the conflict.
  * Check your Net tab in your browser's developer tools when loading a page on your site vs. on the [demo Joomla site](http://joomla.demo.civicrm.org/). Are there any errors, or unusual JavaScript files on your live site compared to the demo? If so, identify their source.
