Widget "Popular Post" not working

Hey there,

I changed my theme to “evolve” last week and I still have some minor issues with it. I am using the widget, that came with the theme, where the user can choose between the 3 most popular posts, the 3 lasts posts and the 3 last comments. This widget shows the last posts and comments but not the most popular.
Any Ideas?

I already deactivated all of the other plugins, doesnt help.
