After an Update without change of the Versionumber the PlugIns works now.
So, its time to start a wish list for the second-best WordPress plugin (after Magic fields):
- widgets with Lightbox Dialogs should work, like Image Widget (in this forum once there was a solution posted, but i can not find it anymore)
- a more compact dialog for selecting widgets, which i can place in the right column, or - if possible - drag and drop of widgets from the middle column to an sidebar container in the right column with real preview (it is for the future of wordpress)
Thank you very much for further development
