This all worked just a few weeks ago (before I updated my WP)
I'm trying to add some new pages to my site and I'm having trouble with any of the java based buttons (add image, etc). Even the Screen Options & Help buttons don't do anything when clicked (however these buttons do work from my dashboard screen).
I did these steps to try to fix
- reinstalled 3.5.1
- deactivated all plugins
- manually replaced all WordPress files except for wp-content via FTP
- switched theme to twenty twelve
I did this:
Added define('SCRIPT_DEBUG', true);to the bottom of your wp-config.php file (just before the require_once line).
Here's the result
Uncaught TypeError: Cannot read property 'length' of undefined jquery.js:2
Uncaught TypeError: Object [object Object] has no method 'uniqueId' jquery.ui.tabs.min.js:5
