Frequently Asked Questions

Can I have multiple themes installed?

Yes, you can install multiple themes, but only one can be active at a time. However, keep unused themes updated or delete them for security.

What’s the difference between installing and activating?

Installing copies theme files to your server. Activating makes the theme live on your site. You must do both for the theme to work.

How do I update an installed theme?

Go to Appearance → Themes, click on the theme, and if an update is available, click the Update button. Always backup before updating.

Can I switch themes without losing content?

Your content (posts, pages, media) stays when switching themes. However, theme-specific settings, widgets, and customizations may need reconfiguring.
