All of a sudden the thickbox functionality in the wordpress admin seems to have died and I'm having a hard time figuring out why that is and how to fix it.
Clicking the featured image button loads the content into the window rather than a modal. Clicking the edit beside 'published' in the 'publish' box does nothing at all (which I recognize isn't thickbox, so I'm thinking it has to be something else).
I'm assuming this is something to do with either jQuery or thickbox, but I'm not sure how to figure out where the problem is and I couldn't find another question with the same errors. Unfortunately it's on the live site (so I can't turn on wp-debug) and when I made a mirror to my local server the problem didn't show up.
