Uncaught TypeError: Object [object Object] has no method ‘wpdialog’

I’ve been looking on Stack Overflow and through the WordPress forums to an answer to this issue, but I can’t seem to find it. I’ll detail the issue, what I’ve done, and what I know.

We’ve got two sites, a development environment and a live environment. At this time, both code bases are synced via GitHub and there are no differences in the files (excluding DB credentials in bb-config.php and wp-config.php). Botha are running WP 3.5.2. On the production site, if you go to add or edit a custom post type (Articles, using the standard WP TinyMCE editor) and try to hyperlink something, nothing happens. On the development site, I can add a hyperlink no problem. In the JS console on the production site I see the following errors.

Uncaught TypeError: Cannot call method 'add' of undefined load-scripts.php:466
Uncaught TypeError: Object [object Object] has no method 'powerTip' myscript.js:8
Uncaught TypeError: Cannot call method 'addListener' of undefined
Uncaught TypeError: Object [object Object] has no method 'wpdialog'

This error: Uncaught TypeError: Object [object Object] has no method 'wpdialog' is the one that shows up only after I click the hyperlink button in the post editor. I’ve checked the source of both sites, and they are the same, minus different subdomains.

I deactivated all plugins, and tried it again. Same issue. Reinstalled WP 3.5.2 manually and automatically, still persists. Tried clearing all caching. Still persists. I can’t deactivate the theme, because then custom post type goes away. I’ve looked to make sure jQuery isn’t being referenced twice.

All the reported issues I’ve seen here and on the WordPress forums have been resolved by deactivating plugins, reinstalling WP, or deactivating the theme. But, those don’t work for me (minus the deactivating the theme, which I explained above).

I’m lost on this one, and not being able to add links is a major problem. We can use in the HTML editor, but the writers aren’t going to know to do that, so any help in solving this problem would be wonderful. Thanks in advance!
