another issue i see in your previous screen shot is that you have both Dynamic Web Charts and Dynamic Flash charts extensions installed, you should only install Dynamic Web Charts. Dynamic Flash Charts is not compatible.
I would not install every extension at one time, i would only install the ones you need to use.
At this point, i think the configuration folder has become corrupted, you should rename the configuration folder, then uninstall all of the extensions form the extension manager, and re install only the extensions that you need to use.
