XML-RPC Error (404): Unknown error

Friends after a bitter struggle, I am asking for help, after all configured back joomdle enf of the same does not indicate any error in checking the system, but when I ask to list the course in front - end for some menu item reports the same error XML-RPC 404, but I can see the users in the backend, but own back end when I ask you to list the courses shows the same error.
