As a Worldserver Administrator, in the User Type associated with the affected user(s), under the
REST API & New UI section, enable these 2 permissions
Users > Can read all users:and click
Save to save your change. The user will be able to access the Tasks page.
Note: this change does not mean that the user will be able to view other Users' settings under
Management > Users. The ability of viewing and/or changing Users is controlled by a different permission under the
Management Tab section of the User Types. This permission does not need to be enabled to address the issue explained in this article.
