This is a basic question. Could you please tell me how can I define a default template for Problem Module for all the users. I know that this can be done in each computer but I want set it up for all the users.
As Err mentioned, in the definition of the roles for your users, you can assign the default templates, views, forms that you want for all users in that role and if have several roles you can configure the same template for all or a diferent one.
In the image attached there is the configuration path for this.
