I am working on a blog that uses a theme customized by a web designer. The design was created 2 years ago and is now outdated. Because I have limited design background, I am trying to replace this theme with a free wordpress theme (Imbalance 2), and I have a couple of questions:
1) If I install the new theme, will it automatically activate the theme?
2) How can I determine whether replacing the customized theme will mess up any current features of the blog?
Thanks so much!
