I have just installed and started customizing the theme. However I cannot change/get rid of the sample 'About me' box, which says 'This is your Third Bottom Widget box (Bottom Widget 3). To edit please go to Appearance > Widgets and choose 3rd widget from the top in area second called Bottom Widget 3. Title is also manageable from widgets as well.'
When I go to the widgets, this Third Box does not contain anything, therefore I cannot modify this.
