Troubleshooting Common Display and Layout Issues in LiteSpeed Cache

LiteSpeed Cache is a powerful optimization plugin, but its aggressive caching and optimization features can sometimes conflict with themes and page builders, leading to unexpected display problems. Based on community reports, this guide covers the most common layout issues and how to resolve them.

Common Symptoms

Users often report issues such as:

  • Images not loading in sliders or galleries.
  • CSS styles breaking, causing incorrect fonts, spacing, or element sizes.
  • Page builder elements (like Oxygen, Elementor, or WPBakery widgets) not displaying correctly or appearing in one column.
  • Visual problems that only occur when logged out or when viewing cached pages.

Why This Happens

These problems are typically not bugs, but rather side effects of how optimization works. The plugin modifies HTML, CSS, and JavaScript to improve performance. This can sometimes:

  • Combine or minify files in a way that conflicts with a theme's or plugin's code.
  • Serve a cached version of a page that is missing dynamically loaded elements.
  • Optimize scripts that are necessary for the proper rendering of complex page builder layouts.

How to Troubleshoot

Follow these steps to identify and fix the problem. It's recommended to test after each step.

1. Generate a Report Number

Before making any changes, generate a report ID from within the plugin. This creates a snapshot of your settings which can be useful for further troubleshooting.

  1. Navigate to LiteSpeed Cache -> Toolbox -> Report.
  2. Click "Send to LiteSpeed".
  3. Note the 8-character report number that appears (e.g., IBGRLNQR).

2. Disable Optimization Features (Most Common Fix)

The most frequent cause of display issues is CSS/JS optimization. Start by temporarily turning these off.

  1. Go to LiteSpeed Cache -> Page Optimization.
  2. In the CSS Settings section, turn off CSS Minify and CSS Combine.
  3. In the JS Settings section, turn off JS Minify and JS Combine.
  4. Scroll to the top and click Purge All -> Purge All to clear the cache.
  5. Check your site to see if the issue is resolved.

3. Exclude Problematic Pages

If a specific page (like your homepage) is broken, you can tell the plugin not to apply certain optimizations to it.

  1. Go to LiteSpeed Cache -> Page Optimization -> Tuning.
  2. Find the UCSS Exclude URI setting.
  3. Add the path to the problematic page (e.g., / for the homepage, /product/booking/ for a specific product page).
  4. Save changes and Purge All.

4. Check ESI Settings

If users are seeing the wrong personal data (e.g., another user's cart or account info), the ESI (Edge Side Includes) feature might be misconfigured.

  1. Go to LiteSpeed Cache -> Cache -> ESI.
  2. Try turning ESI to Off.
  3. Save changes and Purge All.

5. Reset to Default Settings

If you're unsure which setting caused the conflict, a reset can often provide a clean slate.

  1. Navigate to LiteSpeed Cache -> Toolbox -> Import/Export.
  2. Click the "Reset to Default Settings" button.
  3. Reconfigure any essential settings you need and test your site.

When to Provide More Information

If the steps above do not resolve your issue, you will help others assist you by providing:

  • The Report Number from the plugin.
  • The exact URL where the problem occurs.
  • A clear description or screenshot of what the page should look like versus what it does look like.
  • Any error messages visible in the browser's console (F12 -> Console tab).

By methodically testing these common solutions, you can often resolve display issues without sacrificing the significant speed benefits that LiteSpeed Cache provides.
