Event not opening

Hi, when i click the Event button on the home page, then opens only the home page
You can try this
(Sorry for my english)
http://www.sonsuzbilinc.com
Please click to Etkinlik Takvimi (it’s means event calendar)
Then opens the home page
and in footbar is the same problem
When i click the “Hepsini gör Etkinlikler” ( all the events see) don’t work

When i go to the link without button, then the event calender page opens
http://www.sonsuzbilinc.com/aylaaydin/events
What can we do for that?

Thank you
