The log message and the error message in the title are different. Are you trying to uninstall stack? or create a new instance? Can you provide more info

I'm not sure but i think, the title is the message i saw in dashboard popup. And the log is from log. And yes I reinstalled packstack allinone. So i removed than reinstall
