We've installed Image Handler just fine on a few other sites but we can't get it working properly on a new site we're working on. It's on the same server as these other successful installs, so I have no idea what's going on. After installation it wasn't resizing the images at all. I tried to reinstall and now after that every time you visit the Image Handler page in admin, it just says "Image Handler 2, Version 2.0" and that's it. The rest of the page (including footer) isn't loading. No errors (and yes, all error displays are turned on).

Any ideas? Very strange.
