In Wilcity, all Expired Events will not be hidden automatically.
So, What is an expired Event?
Please click on Events -> Your Event -> Event Settings. If your event date is empty or Today is greater than Event Ends On, this Event has been expired

To resolve this issue, there is 2 solutions:
- You should set up Event Settings and make sure that the Ends on is greater than today
- Or you can go to Appearance -> Theme Options -> Search Settings -> Showing Expired Events: Yes
