Custom Google Search Widget No Longer Working In UberMenu

We have a Custom Google Search widget in an UberMenu menu item that is no longer working. Here's a screenshot of what it says now:

I don't know how the widget got removed from the UberMenu item, but when I add it back in there the page goes 502. I'm not sure if this is a support request for WPMU for the Custom Google Search plugin or UberMenu, so I'm opening a support request with both.
