If you have hosted Smart School on your local server and want to use in local LAN network then your Smart School hosting machine should have static ip address (not be dynamic assigned by your modem DHCP). Here suppose your server hosting machine have ip address 192.168.1.2 then when you are installing Smart School then you should type 192.168.1.2/myschool/ not localhost/myschool/ other wise you can not access Smart School from other computers in your LAN and will redirect to localhost/myschool/ url. Now if you have installed Smart School using localhost/myschool/ then you can correct this by editing base_url value in file /application/config/config.php . In this file change localhostto your hosting server static ip address like 192.168.1.2 .
