Hi
By default, Registered users won't have permission to upload document. Only users who has Create permission can upload documents. If you don't want any users to be able to upload documents, you can follow the steps below :
1. Go to EDocman -> Dashboard, click on Options button in the toolbar .
2. Click on the groups you don't want to be able to upload documents, set Create permission to Denied .
After that, it will work as expected .
