Your ROOT_URL in app.ini is http://159.89.207.79:3000/ but you are visiting http://9.cron.my.id:3000/tribikram/AplusAgency/src/branch/aplus%238/public/admin/plugins/jquery-mapael/maps/README.txt
You should set ROOT_URL correctly, otherwise the web may not work correctly.
Additional maps are stored in the repository neveldo/mapael-maps
