Hi, I have access to the component (backend) as super admin, but not for an other created group. I read somwehere that the parent group (public) should be set to 'inherit' for the groups based on this public group to be able to get access. But I can not change the setting s of the public group, not even as a super admin. The option is greyed out. How do I give a group access to the component in the backend?

That are some permissions that can't be given to the public group, although it appears as denied this shouldn't affect the other groups.

to be able to access the backend the user must be in a group that have the permission "Manage Comments" set to allowed.
