A fresh blog design is exciting. Discovering your sidebar disappeared is less exciting. Give yourself a way back before changing the theme, then test the parts readers actually use.
Save the current setup
Back up your existing theme using Blogger’s theme options and follow the official guidance for your account’s current interface. Record important widgets, navigation links, custom code, and analytics settings. Theme backups and content backups serve different purposes, so preserve both as appropriate.
Apply the new theme carefully
Use Blogger’s supported theme tools or the template author’s documented installation method. If you received a package, identify the correct theme file before uploading. Avoid pasting unfamiliar code blindly. A separate test blog can help you evaluate layout and widgets before changing the main one.
Check more than the home page
Open an article, a label page, search, and the mobile menu. Test contact and subscription widgets, image crops, long titles, and any advertising areas. Compare with your notes and restore the prior theme if the new setup breaks important features you cannot fix immediately.
Your next steps
- Download a backup of the existing theme.
- Record widgets and custom settings.
- Follow official and theme-specific instructions.
- Test article pages, mobile navigation, and forms.
