symfony1.4 on godaddy shared host

Hi,
I am very new to symfony frame work.
I’m having trouble to run symfony 1.4 on Godaddy shared hosting.
I simply copied the project from localhost to the server public folder.
I have two applications in my project
1)Frontend
2)Backend

My front end application is working very fine with the url http://www.mydomain.com
Coming to backend application
home page is displayed well with the URL http://www.mydomain.com/backend_dev.php
but further URLs like http://www.mydomain.com/backend_dev.php/abc or http://www.mydomain.com/backend_dev.php/xyz not working as expected
Giving NO INPUT FILE SPECIFIED message.

Can some one help me to solve this issue

Thanks in advance.
