Cannot add content to panels pages (stuck in overlay) When I try to edit the content of panels pages, I click the add content link in the drop down menu an  drag and drop down menu. The progress indicator appears and turns for a while and then nothing happens. The screen remains with the semi transparent overlay (screenshot below).

Also, drag and drop for reordering the content does not work.

Assuming it is related with an ajax call I checked the chrome console but there seems to be no error.

I am using:
panels 7.x-3.3
ctools 7.x-1.3
jQuery v1.8.3
jQuery UI 1.8.7
jQuery UI Draggable 1.8.7
jQuery UI Droppable 1.8.7

I have been searching for hours now but could not find a related post anywhere.

Any ideas?

(a note: I do not have firebug or facebook modules installed. they are reported to cause a similar problem)
So it turned out to be a jquery version problem.

In case somebody else needs it, here is how I managed to solve it.


Installed the jQuery Update module
went to the module's configuration page (admin/config/development/jquery_update)
selected jQuery Version 1.7


and all my troubles faded away :)
