How to Change a WordPress Theme Safely
WordPress · Self-help guide
Changing a WordPress theme can affect layout, menus, widgets, headers, footers, and custom styling. Before changing themes, take a full backup. If possible, test the new theme on a staging copy first. Install the theme from Appearance, then Themes, but preview it before activating. Check the homepage, blog posts, contact page, shop pages, and mobile layout. After activation, review menus, widgets, logo, colours, and page templates. Some themes use their own page builder features, so switching away may change how content appears. Avoid changing themes during busy periods on a live business website. If the new design causes problems, restore the previous theme or backup and investigate calmly.
