Pairing WordPress and

In order to use, you must pair it with WordPress. Here's how to pair LiteSpeed Cache and in your WordPress admin.

Initiate in WordPress

Request Domain Key

Log into the WordPress dashboard for the domain you’d like to use with Navigate to LiteSpeed Cache > General, and click the Request Domain Key button, on the right side of the Domain Key box.

Approved Domain Key

You will see a notification at the top of the page, indicating that the application was successful. Wait a few minutes and then refresh the page. The Domain Key setting will have been automatically updated with the new key.

What if it doesn't update?

In rare instances, there may be a problem generating a domain key for your site. Here are a few reasons why that might happen.

Domain Key Doesn't Generate

IPs are Masked by Reverse Proxy

If you're using a reverse proxy (like Cloudflare), we may be having difficulty validating our server IP addresses. Learn how to fix this. IPs are Blocked

In order for the WordPress plugin to communicate with, you may need to add IP addresses to your server firewall or security plugin. Please see Adding IPs to Allowlist to learn how. Nodes are Down

If something has happened to the service node(s) that usually service your site, you can have the LiteSpeed Cache plugin redetect the local service nodes. Press the logo in the top right corner of the Current Cloud Nodes in Service box.

Security Plugin is Blocking Access

Some plugins, like Password Protected, can block access to your WordPress REST API. Check the plugin's settings, and look for some way to allow REST API access. In Password Protected, this can be found in the General tab, in the Protected Permissions setting. If you can't find such a setting in the plugin you are using, then you will need to disable the security plugin. services cannot work properly without REST API access.


If it isn't a plugin blocking access to your WordPress REST API, it's possible the API itself is not working properly. See Solving WordPress REST API Issues for more information.

Something Else

If your domain key hasn't updated within 15 minutes, and none of the above scenarios apply, please submit a ticket. We'll be happy to help you pair LiteSpeed Cache and

Next Step

The next step is to create a account. However, you only need to do so if you plan to use the CDN. An account is optional, if you only plan to use the Online Services for WordPress.

There are benefits to a account, though, including a handy dashboard where you can:

  • See detailed usage, statistics & even errors for all services
  • Have the ability to increase the quota limits with an account-level credit balance
  • Set up & manage all CDN options
  • Easily open a support ticket
  • Manage multiple domains in one place


if you choose not to set up a account, then you are finished and you may begin using Image Optimization, Page Optimization, and other non-CDN services immediately.

See Creating a Account to continue.
