With the release of the new User Groups, the previous access levels were discontinued because permissions are now set per group. You can, however, configure user groups to match the rights of the previous access levels.
Matching User Groups with Previous Access Levels
To replicate the previous access levels in the new permissions management, you can configure a group for each access level with corresponding rights. Below you will find an overview per group of each group's rights.
In the Manage User Groups article, you will find all details on how to create groups and a description of each right.
