LiteSpeed Cache has introduced LSCache standard Presets for WordPress, which now lets you use a set of pre-tuned options to optimize any WordPress site using LiteSpeed Cache.
This Knowledge Base article will cover how to use this new feature.
Frequently Asked Questions
I am new to Litespeed Cache, which preset should I apply to?
We recommend using the Advanced Preset as it takes a balanced approach to Optimization and Speed, and you shouldn’t need to manually tweak any settings. That said, if you experience difficulty, you can always revert to your previous settings, or try the Basic Preset.
Can I modify Litespeed Cache settings after setting up this preset?
Yes, it is absolutely possible to edit any options after applying this preset. Standard presets are just an easy way to give you a good base optimization to start with. Most complex websites will need more fine-tuning to achieve their best possible score.
If my website breaks after applying a preset, can I change back to the setting I was before?
Yes, but only if you have previously saved a backup of your settings as instructed. A backup will provide you with a config file of your own website, which you can restore later if needed. Alternatively, you can always use the Basic Preset, which has the default settings.
How should I get more fine-tuning specifically for my website?
You can start with the Advanced Preset, and then go through the options in the Page Optimization section to see what more you’d need. Then try to enable them one by one to get the best for your website.
Are there any known bugs?
Yes. The Domain Key removes itself when you apply a new preset, and requires you to manually refresh your domain key from the General settings. LiteSpeed plans to patch this issue in an upcoming version.
Let’s begin!
Overview of the LiteSpeed Cache Presets
The new presets from LiteSpeed come in 4 stages:
- Essentials

Let’s review what is included and pre-configured in each Stage, below.
