A lot of the unnecessary details are excluded but it still covers every setting and prompt known to occur. It’s been testing with several host providers and several hosting plans. Regardless, if you don’t see something covered you’ve experienced, check out the LiteSpeed Documentation on this subject of “LiteSpeed Cache General Settings“.

Step 1. Install and Activate the LSCache Plugin for WP.

First, ensure you’ve installed and activated the free LSCache plugin, aka the LiteSpeed Cache Plugin for WordPress. When adding a new plugin, find it easy using the search keyword “litespeed”. Here’s what it looks like when locating it.

Step 2. Starting Settings

On the LiteSpeed plugin, tap its “Settings” option. You now have 3 options.

You can accept the recommended default settings for now. There are several options shown from minimal to aggressive caching.
Import any previously saved settings, if you’ve used this plugin before.
Manually decide your own customized settings.

At any point you receive a message indicating a cache service has stopped, e.g., redis or memcached, feel free to go ahead and restart that service. Sometimes changes you’re making require it to be stopped. It’s a good idea to start it up again and keep it actively running when you see those messages.

Step 3. Register for a Free QUIC Cloud Account

Ensure you have an account (free) setup at Quic.Cloud. If you don’t have one yet, register for one. It’s fine to use your current domain for that initial setup but it’s not required to have any domain listed there yet. This post’s procedural steps are designed to do that for you while getting a domain key.

Step 4. Re-enable your Redis or Memcached Service.

After tapping to SAVE your General Settings screen that contains your now populated domain key, tap the notification’s URL named “enable the drop-in”.
You’ll be taken to the Redis or Memcached setting. Just tap the <Enable> button(s) to get those services started again.
Then, return to finish your domain key work by going to WordPress Menu: LiteSpeed Cache | General. You’ll be back to finish the last step on the General Settings screen.

Step 5. Link Domain to QUIC.cloud

After going to the WordPress menu path “LiteSpeed Cache | General”, you’re ready for the final step. You’ve returned to the General Settings screen. Your LiteSpeed domain key is still showing populated (with asterisks) in its text box. Here is your last procedure to follow.

Now, tap the <Link to QUIC.cloud> button.
Then, respond to login to your QUIC.cloud account.
Respond “Yes” to the prompt.
Tap <Continue> (or <Submit>) for completion.

Step 6. Final Follow-ups to Linking your Domain to QUIC.cloud

Now that you’ve linked your domain name to QUIC.cloud, you’ll want to ensure your host provider allows all the QUIC.cloud IP addresses shown LiteSpeed Cache | General Settings screen. By allow, I do mean to pass through their firewall for your LiteSpeed cache service. They’re also listed in the URL named Current Online Server IPs.

One way is to copy and paste the list into a support ticket but also send the URL, in case they have a way to maintain that list. And, in your request, if you’re not using a shared server, you’ll want to ask them to assign the permissions to the entire server, not just to your domain. That way, if you add other future domains (or also addon domains or subdomains) on that server, you won’t have to repeat that support ticket again.

Step 7. Confirm Your QUIC Cloud Domain Key is Working

After about an hour or so, you’ll notice the “nodes” will start to expand and appear on that General Settings screen. If not, you might have to wait until your support ticket has been concluded with the IP address permissions assigned.

Step 8. Export to Save Your LiteSpeed Settings

From the LiteSpeed menu, go to “Toolbox” and tap the tab “Import / Export”. Here you have several options:

You can review that screen for saving your settings using the export function.
Also, you can use its import function whenever you need to restore them from the last saved version.
Finally, it also has a <Reset Settings> feature for starting completely over back to the default starting point.
