                    Hi, 
I have installed my classipress. I have created a sub theme and into my theme directory i have copied some files: 
- footer.php
- header.php
- index.php
- sidebar.php
- style.css
I have also copied the entire includes folder into my sub theme. 
I am doing this to keep the original classipress as it is. I have edited the mytheme/includes/theme-header.php file and removed some things I don't need. 
However, what I removed from the file now comes from the original classipress files. How can I stop this behaviour? I do not want to remove things from the originals files.
Hope this makes sense.
