regarding updating classipress 3.3 to newer version
Why I just got the classipress theme I was not familiar with the forum. I had no idea about installing child theme if If needed to have my desired changes done to the site. So, I made changes to green tpl. How will I be able to go about doing latest update to newer version and even newer version wordpress without losing my changes made to site?
Is it a must that I have to use a child theme in order to do updates?
