bei mir war das Problem auch mal als ich AdminTag rumgespielt habe. Hab das Problem behoben indem ich es wieder deaktivierte.

if you set "needAdminNameTag" to "true", this string needs to be a part of the admins name, or he can't use infiSTAR Admin Menu!
example names: "[Admin] infiSTAR" or "infiSTAR [Admin]"
note: this is case sensitive as well, meaning "infiSTAR [admin]" would not work as we set it in our example to "[Admin]"

needAdminNameTag = "false";
AdminNameTag = "[Admin]";
