Search for the title of the widget (Example for Printfriendly widget).

Edit the code from (Example):

<b:widget id='HTML1' locked='false' title='Print PDF powered by www.printfriendly.com' type='HTML'>
<b:includable id='main'>

<b:widget id='HTML1' locked='false' title='Print PDF powered by www.printfriendly.com' type='HTML'>
<b:includable id='main'>
