Can turn off Poll on Q&A site
From QEngine version 2.0, Poll was available to help users conveniently ask questions and make small surveys out of it. In this version, another option for Poll is added in the Dashboard, so that you can choose whether to enable or disable Poll on your Q&A site. 
In Dashboard: Engine Settings →Poll.
