I was not able to solve by myself an issue with Custom sidebar Pro. This is how our sidebar looks normally: http://krisstelljes.staging.wpengine.com/selbstmotivation-lernen/ (looks like this on my Mac: http://screencast.com/t/ee13ywqevpU)
And this is how the Custom Sidebar looks with the very same widgets inside: http://krisstelljes.staging.wpengine.com/facebook-anzeigen/ (looks like this on my Mac: http://screencast.com/t/cTfSvkKYWD)
So it looks kind of broken and display not correctly, although it has the same elements in it (for testing).
Can anyone help me to find a way to make it work?
