I had a lot of trouble because in Weaver II I had one column on the right side and it only showed part way down the page.
The answer was to do two things
- Go to “Appearance | Weaver II Pro Admin | Main Options | Layout”. Under “Container & Sidebar Color Flow” ensure that “Flow color to bottom” is selected.
- On the same page under “Right Side, One Column” ensure the “Background” is set to the same color as the widget background.
Remember the widget is inside the sidebar and it’s the sidebar that extends to the bottom of the page so you need to have them both in sync.
