Switching WordPress themes can be an exciting step toward a fresh look or new functionality. However, for many users, it turns into a frustrating experience when they realize that shortcodes are no longer working and their carefully designed layouts are broken. This situation often arises due to conflicts between the old theme’s unique shortcodes and the new one’s incompatibility, leading to lost content and mangled designs. Fortunately, there are ways to recover from this—and even prevent it in the future.
TL;DR
Changing themes can break shortcodes and layouts, especially if the previous theme used custom shortcodes or integrated page builders. To recover, identify missing shortcodes, use plugins to restore them, or rebuild using more compatible tools. Backups and child themes are life-savers. Users who faced these issues turned to recovery plugins, manual fixes, and modular builder tools to salvage their websites and retain content.
Why Do Layouts Break When Switching WordPress Themes?
When you switch a theme, you’re not just changing the look and feel—you may also lose functions that were native to the old theme. Many themes use proprietary shortcodes or embed page builder integrations that don’t carry over to a new theme.
Common consequences of a theme switch include:
- Shortcodes displayed as text – For example, instead of turning into a styled button or column, you see
[fancy_button color="blue"]Click Here[/fancy_button]. - Disorganized page structure – Layouts built with a theme-specific page builder may lose grid alignment or spacing.
- Broken sliders or galleries – Especially if the media elements were built using theme-specific tools.
This happens because shortcodes and layout-building functionalities are often built into themes rather than plugins or WordPress core, making them non-transferable.
Recovering Deleted Shortcodes: What You Can Do
If you notice your pages now overflow with useless shortcodes or empty areas where once content lived, don’t panic. Several steps can help you bring back critical content, even without reverting to the old theme.
1. Reinstall the Old Theme Temporarily
Reverting temporarily to your previous theme is the fastest way to identify and copy precise shortcode content. This allows you to edit posts or pages and take note of which shortcodes were used, so you can replicate their look with universal tools.
When doing this:
- Use a staging environment, like LocalWP or a plugin such as WP Staging.
- Take screenshots and copy shortcode syntax for future comparison.
2. Use a Plugin to Detect Orphaned Shortcodes
There are plugins like Shortcode Cleaner Lite and Remove Orphan Shortcodes that help you identify shortcodes that are no longer linked to functional output. They can either remove them cleanly or help flag them for manual replacement.
This is a great step for:
- Cleaning up broken-looking front-end sections
- Figuring out which shortcodes are no longer being parsed by any plugin or theme
3. Reassign Shortcodes Using a Universal Shortcode Plugin
If you want to retain the functionality of specific shortcodes (like buttons or tabs), you may be able to recreate them using a universal shortcode plugin such as:
- Shortcodes Ultimate
- WP Shortcode by MyThemeShop
You can remap some old shortcodes or replace them with new ones that closely mimic the original design.
Fixing Broken Layouts and Designs
Once shortcodes are handled, you’re likely still faced with uneven columns, missing sliders, or header content that vanished. These broken layouts are often from sections built with theme-specific page builders or custom widgets.
Here’s what you can do:
1. Identify the Page Builder Used
Some themes bundle their own page builders (like WPBakery, King Composer, or Muffin Builder). Switching themes often disables the associated editor, which takes your layout with it.
To restore access:
- Reinstall the same page builder plugin that came with your previous theme
- Enable access to posts/pages through settings
- Copy the content into a new page builder (e.g., Elementor or Gutenberg) for long-term compatibility

2. Use Reusable Blocks for Common Elements
Especially in the case of Gutenberg or Elementor, rebuilding key designs like call-to-actions or testimonials as reusable blocks can save time and prevent future layout loss. These blocks are theme-independent and stay functional even if you switch appearance elements.
3. Restore Backups Selectively
If you use a tool like UpdraftPlus or BlogVault and have recent backups, you don’t necessarily have to restore the entire site. Many of these tools let you restore only specific pages, parts of your database, or media files, allowing you to selectively bring back content without losing the new theme environment.
User Stories: What Others Did to Reclaim Their Websites
Case 1: Moving from Avada to Astra
One user who had built their entire site with Avada’s Fusion Builder switched to Astra and was shocked to find blank pages. None of the original Fusion shortcodes were recognized. Their recovery process involved:
- Reinstalling Avada in a staging environment
- Copying raw content into a JSON file
- Rebuilding the layout in Elementor using saved text and images
They reported a cleaner, faster site but noted it took 12–15 hours of manual rebuilding.

Case 2: Salvaging Lost Shortcodes with Custom Plugin
Another user developed their own lightweight shortcode plugin that mimicked their origin theme’s functionality. For example, they recreated [testimonial-box] and [pricing-table]. They applied styling inside the plugin manually with custom CSS, preserving the look while removing their dependency on the old theme.
This approach is especially useful for developers or site owners comfortable with code but may not be suitable for everyday users with limited technical skills.
Case 3: Cleaning With Shortcode Cleaner and Manual Rewrite
One blogger switched to a barebones theme like GeneratePress and found their content littered with unsightly code blocks. They used the Shortcode Cleaner plugin to eliminate unused tags, then manually replaced the sections with Gutenberg patterns.
The key lesson? Keep shortcodes and content layout handled by plugins—not the theme—whenever possible.
Best Practices to Prevent This in the Future
Recovering from broken shortcodes and designs is time-consuming. Fortunately, you can take steps now to avoid facing the same headache again:
- Use modular page builders like Elementor or Gutenberg Blocks that don’t lock you into a single theme.
- Keep shortcodes within a custom plugin or shortcode library so they are theme-agnostic.
- Always backup your site before switching themes.
- Use a staging site to preview theme changes before going live.
- Document your page structure and reusable elements so future rebuilds are easier.
Final Thoughts
Switching themes can feel like you’re tearing down your digital house—but with the right tools, strategy, and understanding, you can rebuild stronger than ever. While deleted shortcodes and broken layouts are frustrating, they’re far from catastrophic. By using staging environments, recovery plugins, and modern block tools, users across different skill levels have restored—and even improved—their websites successfully.
The real takeaway? Make your content and functionality portable. When your tools are broader than a specific theme, you gain the freedom to redesign without losing what you’ve built. Plan ahead, backup first, and treat your shortcodes as part of your long-term strategy—not just a temporary decorative solution.
