Hello,  
I am using Ionic version 1.7.6 . I am seeing this error in my application console and my app gets stuck in splash page because of this:  
Uncaught Error: [$injector:unpr] Unknown provider: $logmProvider \<- $logm \<- $ionicNavBarDelegate \<- $ionicViewSwitcher \<- $ionicHistory

The file which this error refers to, has no logmProvider or logm written anywhere. It only has ionicHistory, which works properly in my debug mode but not in release mode.  
I think it says ionicNavBarDelegate has logm, but can even I have access to it? Where does it come from? I haven’t changed it and I even don’t know where can I see its data.

Any ideas? Is it a common problem?
