I had the same question. Thanks for the tip.
For anyone else that has the same question, the specific steps that I took were to go to “Appearance : Widgets” and then I added the “MT Popular Posts” to the “Home Popular Widget Area”. I am sure you could add another of the available widgets to the “Home Popular Widget Area” with similar success.
My guess is that you will want to change the image size to 563×353 px and that it will then work.
I had the same question, but the image went away when I added an advertisement in “Home Page Ads (Mid Section)”, which can be added under “Theme Options : Advertising”.
I had the same problem. At first I interpreted “clear cache” to mean that I should “flush cache” within my WordPress dashboard. That did not work, but clearing the cache in my Chrome browser was successful.
