Question:
I chose a template layout when I installed EE, but now I want to choose another, what are the steps I need to take to choose a different layout template?
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.
You can find existing Site Themes at the Site Themes Downloads Page. Download the template you’d like to use.
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.
NOTE: After you’ve created your new weblog and template group, you can change the following values in each template.
{assign_variable:my_weblog="howto"}
{assign_variable:my_template_group="site"}
Set the value of my_template_group to match the name of your existing template group name.
After you’ve made all the changes to your new template group, rename your initial template group to something like site_backup, and your new template group to your initial template group name.
So if you created newblog for a template group name, and site is your original template group name, rename site to site_backup and newblog to site.
Disclaimer: Prior to attempting this, make backup copies of your templates.
