Log file in a chat application

Hello everyone, I am a newbie to web development.
I have an issue regarding a basic chat application that I am working on right now.
The following is the link from which I am currently working right now.
http://code.tutsplus.com/tutorials/how-to-create-a-simple-web-based-chat-application--net-5931
The chat conversation is not being displayed. Please help me

 

well there can be a problem anywhere ... 1) this tutorial is almost 4 years old and there are a lot of changes (however with this old ajax library and code it could work); 2) you can have any bug in your code (no offence) and it's hard to find bug without code

btw take a look here (http://thewoovee.com/blog/simple-chat-system-using-php-and-jquery/) it looks like similar tutorial what you posted + you can download source code and try demo

 

Could you please help me if I post the code here?

 

I can promise you nothing but I'll take a look on it.

 

I have worked according to the link you have given me, but instead of viewing the chat content, the page is directing to the login page.

 

it's weird because I downloaded source code and it's work on localhost/vps without problem

(On the login page you write your nickname, then press Enter and you'll see the chat content)
