I am trying to Enable an app (from openpublic) but it just gives the message "App not enabled". However, it gives no reason...
Do you mean "Enable App"? A have the same trouble with the Blog app.
It looks as apps cannot resolve dependencies.
Is this still an issue?
Yes, still an issue. If one or more dependencies is missing, an app will fail to install and give the message "[App name] App Not Enabled". #1611888: Can't Enable Rotating Banner App is an instance of this issue.
