Over the last few years, I’ve done numerous WordPress website redesigns.
In every case so far, I’ve helped clients switch to a new WordPress theme. And when you switch to a new WordPress theme, so many parts of your website can break.
Here is a “WordPress Theme Switch Checklist” you can use to reduce the risk of your WordPress website breaking when doing that.
- Shortcodes that your existing theme provides.
- Make a list of shortcodes that your old theme supports.
- Search for it across your pages, posts and custom post types.
- Remove or replace it with similar functionality.
- This includes everything like Facebook pixel, Google Analytics, Hubspot tracking code etc.
- Usually it might be inserted inside your theme’s option panel.
- Re-insert them after you switch to the new theme
- A better way is to use Google Tag Manager for all your scripts so that there is only one script on your website.
- Pages created with different page builders
- Manually check pages created with page builders (like Elementor, Thrive Architect etc.) to see if they render properly in your new theme.
- Custom CSS or JS from WordPress Customizer panel
- This is an additional place where your developer(s) might have inserted codes.
- This has to be done even if you are simply switching to a Child theme.
- Are you switching from an old theme you bought from ThemeForest?
- Check for revolution sliders embedded across your site.
- If you were using Visual Composer (which I advice you to get rid of), you might have to recreate most of your pages
- WooCommerce generated pages (cart, checkout, thank you etc.)
- Check if your new theme provides the same WooCommerce template overrides.
- Take a backup before switching. If your hosting doesn’t support it, use UpdraftPlus plugin. Its free.
