LiteSpeed Cache und wie man Mobile Caching richtig konfiguriert

Most WordPress themes today are responsive — they adapt to mobile screens without requiring a separate mobile version. Yet some caching plugins, like LiteSpeed Cache, offer a separate mobile cache option. At first glance, it might seem helpful. But in most cases, enabling mobile caching causes more harm than good.

Why you shouldn’t enable mobile caching

When mobile caching is enabled, LiteSpeed creates two versions of your site cache: one for desktop and another for mobile. This results in:

• Double the server load: Every page is cached twice.

• Unbalanced warming: Mobile visitors warm the mobile cache, while desktop users often get cold pages.

• Lower PageSpeed scores: Google measures average performance over time. Cold cache leads to worse scores, especially for desktop.

• Confusing cache management: Two sets of cache mean more risk of layout issues and outdated content.

How to fix it the right way

There are two safe methods to disable mobile cache in LiteSpeed Cache and avoid these problems:

Method 1: The fast and safe way

1. In the LiteSpeed Cache plugin, choose Basic Preset under Preset Settings.

2. Export your settings file.

3. In the exported .data file, find and change:
   "cache-mobile",true → "cache-mobile",false

4. Save the file.

5. Import it back into LiteSpeed Cache.

✅ You now have a setup without mobile cache and ready to configure other options manually.

Method 2: Set it up manually from scratch

If you want full control, use these settings:

• Do not enable mobile caching in the general cache tab.

• Enable minification for CSS, JS, HTML.

• Verwenden Guest Optimization and/or Critical CSS.

• Verwenden browser cache and set TTLs smartly.

• Leave all optimization options that affect mobile/desktop separation disabled.

This guarantees a unified cache, consistent speed, and fewer bugs.

After selecting the “Recommended” preset, even if you disable the mobile cache checkbox, LiteSpeed still stores it in memory as enabled. That’s why exporting and re-importing the config file is often necessary.
