Question: How can I use a different theme with my current weblog, or with a new weblog?

Answer: ExpressionEngine doesn’t support one click theming, but you can install a new weblog (or data container) that will let you pick a different theme.

First, you’ll need to upload your new theme into your /themes/site_themes directory.

Then you’ll need to create a new weblog. During the creation process, you can choose Duplicate an Existing Group, and pick which template you want to use.
