I have installed prestashop,but facing some problem..?

I have installed prestashop but I can see its back end web page and can login into it but front end shop page is not opening up in my browser an开发者_如何转开发d it is showing error.I dont know what is the reason?

Have I made a mistake in understanding prestashop..???Is it to be installed with some other CMS or it is self sufficient ? I have no other file except prestashop files in my web directory.
