LiteSpeed Cache for WordPress (LSCWP) plugin v3.0 was in development for some time and now they have launched the much-awaited public version which includes a complete revamp of the GUI design and additions of many features.
For availing features online services like Image Optimization, generate Critical CSS, Low-Quality Image Placeholders, QUIC.cloud CDN Cache etc., we need to generate a domain key. This process is automated. Only if you need to use QUIC.cloud CDN, you need to link the account to quic.cloud dashboard. If you are not using it and just want other features only, users can get online services as an anonymous user by just creating a domain key.
1.Login to the WordPress admin dashboard.
2. Select Litespeed cache >> General
3. On that page, there will be a box for the domain key. Click on the “Apply Domain Key” button.
4. After that, you’ll get a success message and refresh the page afterward.
5. After refreshing, the box should automatically be filled with the key and click “Save changes”
6. Once you save, click “Link to QUIC.cloud” if you wish to see all statistics and enable QUIC.cloud CDN
Something about QUIC.cloud
QUIC.cloud is the first and only content delivery network with the ability to cache dynamic WordPress pages. Using QUIC as the transfer protocol, QUIC.cloud will make your website faster and more secure than the competition. QUIC.cloud greatly reduces transmission time to all of your site’s visitors, no matter where they live. Your website is potentially located across the globe from its visitors, but with QUIC.cloud, your content is cached on servers all around the world. When a visitor requests content from your site, a copy is served from the visitor’s nearest server location. By transmitting both static and dynamic content from the closest server, instead of from the main site server, QUIC.cloud dramatically speeds up your site.
This website uses a fully integrated QUIC.cloud CDN with OpenLiteSpeed Web Server. You can see it works. But just remember QUIC.cloud CDN is still in its beta stage and is not recommended for use in heavy production environments at this time. All other LSCWP features including the online service features like Image Optimization, generate Critical CSS, Low-Quality Image Placeholders, etc. are there for quite some time and are mature for production. Feel free to use it.
It is a bit long topic to write QUIC.cloud CDN within this article about new LSCWP and will be a new post mentioning its setup, signing up to quic.cloud and all. Stay tuned for that.
Walkthrough of new LiteSpeed Cache for WordPress (LSCWP) plugin version 184.108.40.206
There is a new nice dashboard that shows the status of the usage of different online services, Page Speed, Page Load Time, cache status, crawler status etc.
In the General Settings, there will be a box for the domain key. Click on the “Apply Domain Key” button. It will contact the LiteSpeed servers and generate a Domain Key which allows you to use the online services. You’ll get a success message and refresh the page afterward.

LiteSpeed Cache Settings is home to many cache tweaks for your WordPress website including settings up enable/disable caches, different TTLs, enable/disable Object Cache, Browser caching aspects etc.
In the LiteSpeed Cache CDN settings, we can enable QUIC.cloud CDN ( in beta stage, requires a sign up with my.quic.cloud), other third-party CDN, and Cloudflare Integration. The “manage” tab helps to manage the Cloudflare caching via their API.
LiteSpeed Cache Image Optimization got some revamp in appearance but functionalities remain the same. Don’t forget to generate domain key again even if you were using it earlier.
Page Optimization settings in LiteSpeed Cache for WordPress plugin got a separate tab in the new version and the settings appear to be the same. It allows us to setup combine and minify settings for CSS, JS, Asynchronous JS, etc.
LiteSpeed Cache Database Optimization feature is now added to the new version of LiteSpeed Cache for WordPress plugin. It allows clear post revisions, drafts, trashed posts & comments, optimize tables, etc. Also, Table engine converter is available to convert tables from MyISAM to InnoDB. The new database summary section shows the top Autoload values and the size it takes. Discussion on Autoload is just outside the scope of this article but too much autoload size is not good as on each page visit, these values are loaded by the WordPress from the options tables. This can slow down your website.
LiteSpeed Cache Crawler section added more fine-tuning for warming up cache and is now linked to QUIC.cloud if you are using it.
Finally, LiteSpeed Cache Toolbox allows you to purge all caches that are generated by the plugins, view logs, import and export settings etc.
This is all about the different tabs available in the new LiteSpeed Cache for WordPress plugin version 3.0 (LSCWP 3.0).
