After upgrading sometime in the past few days, I noticed that the widget was overlapping the widgets below it. The widget background color does not extend below the
<h2> title so it appears to not be contained properly.
But here is the even stranger thing I just discovered: I had the refresh interval set to zero so that only one testimonial would show up at a time. If I change that to anything other than zero, the problem is fixed!
Is anyone else having this problem? Ideas to fix it? In the meantime, I'm just going to set a ridiculously long refresh interval.
