XF 1.5 Recent Activity Blank

We are using XenForo 1.5.14 with the UI.X theme. Recently we noticed that the "Recent Activity" tab of users' profiles is blank. There is nothing there. All of the other profile tabs seem to be fine. What might cause this problem, and how could we go about correcting it? Thank you!

As usual, the first step in identifying the cause of issues such as this is to disable all add-ons and revert to a default style.
