Can't acknowlegde events

[Wilfried]

Hello,

I have a problem with my nagios XI server
All my "single" users can't acknowledge events
when they try to do it they have the following message

Sorry, but you are not authorized to commit the specified command.
Read the section of the documentation that deals with authentication and authorization in the CGIs for more information.
Return from whence you came

I checked the CGI config file
