I am trying to get to the Settings page to try this out (it's exactly what I needed!) but it won't load for me. At first it would give me an error message, Fatal error: Maximum execution time exceeded of 60 seconds. I found a fix for that by adding a higher time limit so it wouldn't time out. But now it just loads with a black screen, and centers the text in the WP menus on the left, which makes me think that it's just not loading completely.
Any ideas? Is it possible that my list of 100s of items in my custom taxonomy could be causing this problem?
