#25 Content - admin_object.cgi gives ERROR

[Anonymous]

In logs it says:
Premature end of script headers: [root]/cgi-
bin/om/admin/admin_object.cgi.
Can't locate [root]/lib/permissions/admin.1.pm at
[root]/lib/permission_layer.pm line 1140.

admin.1.pm is actually admin.1.pm or admin.2.pm or
admin.3.pm

I could create manually those files if I know howTo.

Is there an explication ?
thank you very much.
