You have to add a scriptmanager to the master page.
The easiest way to achieve this is to open the site with the sharepoint designer.
Navigate to your master page: _catalogs/masterpage/….master.
Edit the master page and add the following line directly after the form tag:
<asp:ScriptManager runat="server"/>

Save the master page and the web part should work.
