1.5.1City Dropdown in shipping doesn't show?

Hello everyone,

I added an extenstion, after that the city dorpdown is not being filled, the cities are available in the Admin Panel,
this is my website: http://www.elektroniksigaraevi.biz/
I have searched on the web, read a lot of posts, but it didn't work, we use CloudFlare,

What can I do?

Cntact the developer of the extension

'Cities' are not a part of the defautl OpenCart install
