Plugin broke after update, doesn't return any results

Here’s an image what happens:

1. First one occurs when I double click the search field
2. In the second one I try to search things starting with “oma”, which returned multiple results before update, but not anymore

I haven’t installed any new plugins or changed anything else so I’m quite sure it’s some sort of bug.

I’m running Genesis Theme Framework if that helps!
