Can not add content to panels Environment:


Drupal 7
Modules: Page manager, Devel generate, panels in-Place Editor, Panels, CTools, jquery-module


I defined a 3 column design but I can not add any content to any panel (superior, left side, middle column, right side...)



Any idea what it can be?
So it turned out to be a jquery version problem.

Here is how I sort it out.

I have installed the jQuery Update module with version 1.10 selected and I had to change it to version jQuery Version 1.7 and all the gotchas faded away.

I hope this help to anyone else!
