Edit the PAGES! Help Me
 

Hello,i edit the index.php ,login.php pages.But i opened the Notepad++
But i show the Different codes..

Where the Codes? (php,html)
Please help me.

I don't quite get your question, but I hope this helps:

-> The html of the whole page is inside templates. If you are using the main theme, it's inside the main folder in the header.tpl and template.tpl files. Check out Smarty to see how it all works together.
-> The part where the content appears is in the .php pages. Each page is divided in two .php files per MVC convention. For example if you want to edit login page: loginview.php for the part shown to the user (text written - the View) and login.php for the input confirmations and database-related accesses (the Controller)
