QuickManager Edit Resource --> blank page

Hi everyone, I have just upgraded to 1.01 from 0.9.6.3, and I absolutely love it. BUT, I have a small problem with QuickManager.
When I use QuickManager and click "Edit Resource" or "Create Resource" from the front-end, I just gets a blank page (url: index.php?a=27&id=20&quickmanager=1 ).

I did a "clean" upgrade by deleting the old files to avoid any leftovers from 0.9.6.3.

It is not a critical fault as I still can edit from inside the manager, but it would be kind of nice to be able to edit from the front-end.
I’m using the newest version of Firefox by the way.

Thank you in advance. =)

EDIT: In Internet Explorer I see there is a Javascript-error: jQuery is undefined.

Check QuickManager+ plugin configurations settings about loading jQuery in manager and front-end.

Ah D’OH! It’s working now. Somehow jquery-1.3.2.min.js and jquery.colorbox-min.js hadn’t been transferd to the production server /js folder. Now everything is smoth. Thanks for the help Lammikko.
