I installed the Timesheets module along with related modules in my v10 Community Edition installation. It allows me (admin) to add time to projects and tasks for myself and other employees. However, when other employees attempt to add time entries in Timesheets or directly on Project Tasks, they get the following error. I checked permissions and they seem correct. Are Timesheets not permitted on CE or is this a permissions issue? I'm confused because it allowed me to install the module and I can add time entries myself.
