Title
After installing QuickApps the configuration pages are missing from General Application Settings in Central adminDescription
Cause
Application was installed on a WFE where central admin was not installedResolution
To resolve this issue you can push the QuickApps solution out to the central admin server. Once done you should be able to see the configuration options in General Applications again.
Central Admin | System Settings | Manage Farm Solutions | Click quick.apps.wsp | Click Deploy Solution | Choose your Central Admin server and a time to deploy then click OK
Once deployed you should have access to the management pages.
