If the message You are not authorized to access this page appears, please deactivate Borlabs Cookie under the plugins and activate it again.
Version 2.1 introduces custom roles. This allows users other than administrators to have access to Borlabs Cookie. The authorization is called manage_borlabs_cookie and is automatically added to the Administrator user role during the update.
If this did not work, usually deactivating the plugin and then activating it again helps to reassign the permission.
If plugins are used for extended user permissions, please check if the manage_borlabs_cookie permission has been added to the respective users.
