City not mentioned

The weather widget was working perfectly fine, however, over last couple of days we have been observing that it is not displaying the name of the city and displays data as follows:

Partly cloudy
in Unknown
35°C

The site where the widget is used is http://www.stayingurgaon.com. I request your help to sort this out.
Thank you!
