We are not able to log time to dead/complete projects. But, when a user tries to log time - no error message pops up. Is there a way to have an error message generate?

@sueg3 The "+Log Time" button does not appear on the Hours tab of a project if it is marked Dead or Complete (pending those options are deactivated), and on a timesheet, the boxes are greyed out. Can you share some more details as to where these users are trying to log time?

Or are you hoping that Workfront would display the "+Log Time" button, but generate an error message saying something like "This project has been marked complete/dead, no additional hours can be logged" to make it more clear to users? 

I’m thinking that these users do in fact have ability to log time, you may want to check your setup settings. Tasks/projects in time sheets are greyed out if they can’t log time to them and they wouldn’t see the +Log Time button within a project hours tab or task/project updates if they are no longer able to log time to the object. It’s effectively an error message but the functionality is removed…
