Flow Map Error Overlay
Flow maps are also an excellent way to visually inspect the most error-prone pages.
To see the error overlay, check the ERROR checkbox on the upper right-hand corner of the screen.
You will now see the flow map nodes colored in RED or ORANGE depending on the error severity on those pages.
Click on the nodes to see the details, including the number and severity of the errors.
Click on the errors rings to see the error details.
