I want to use Litespeed with their cloud extension, but during the validation, WPML redirects to a 404 page. I am trying to link my Litespeed extension with QUIC.cloud, but the request from the remote server gets redirected to an error page due to the WPML plugin.

You can refer to this ticket, which is not solved: https://wpml.org/forums/topic/i-want-to-use-litespeed-with-their-cloud-extension-but-during-the-validation-wpml-redirect-to-a-40/

Problem: I do not get your notification, so the ticket is closed before I can even review.

The solution proposed does not work. Refreshing the permalinks work when WPML is not activated. If WPML is activated, it does not work

Hi Philippe,
Thank you very much for sharing the credentials requested

Is this a staging site where we can run tests?

Yes, this is a copy of the original website. You can run tests, no worries.

Hi Philippe,

I tested the site in a minimal setup, only the Litespeed Cache plugin activated and a default WordPress theme, but the issue persists. I created a video for you showing the steps I followed and the results obtained: hidden link

As I mentioned in the video, I recommend contacting your hosting providers and the Litespeed Cache support service to take a deeper look at this issue and isolate its cause.

Best regards,
Carlos

Hi Carlos,

Thanks for your tests.

Indeed, you need to resave the permalink after having de-activated WPML and you will see that you will reach the QUIC serveur.

It seems that WPML is blocking a redirect that the Litespeed extension is doing to connect.

To activate, QUIC cloud server do a verification on the following URL:

hidden link

This request is redirected to hidden link by WPML :

< x-redirect-by: WPML
< location: hidden link

The server then respond with a 404 :

152.53.38.14 - - [20/Nov/2025:14:50:43 +0100] "GET /?rest_route=%2Flitespeed%2Fv3%2Fwp_rest_echo HTTP/1.1" 404 149 "hidden link" "QUIC cloud bot/1.0"

The root problem is that WPML is doing a redirect while it should not.

If you start again from the existing state of dev.pbm-center.ch, you can go to the litespeed plugin and click on activate. You will see the screen attached. Go back and activate WPML and you will see the error message if you try to do the same activation.

Thanks,
Philippe

Hi Philippe,
Thank you very much for your message.

However, with the WPML plugins deactivated the URL throws a 404 error: hidden link and the URL hidden link is the same; it only uses different symbols for the slashes ( / = %2F)

Hi Carlos,

Not sure, this is getting too technical for me. But what I tested is that without WPML (and the permalink resaved), it works, while when WPML is enabled, it does not work. I did it several times on the dev site and could replicate this.

So there is a link between WPML and the plugin not being able to connect.

Thanks
Philippe

Hi Philippe,

Let's try the following, because if there is a compatibility issue, I will escalate this ticket to our compatibility team.

1.- I kindly ask you to connect to the Litespeed Cloud with the WPML plugins deactivated. If you succeed, then activate the WPML plugins and check the results.

2.- If the issue appears when you activate the WPML plugins after connecting to the cloud service, then I will create a sandbox site with a new WordPress + WPML + Litespeed installation, and if the issue persists there, then I will escalate directly.

Those are the only steps needed 🙂

Hi Carlos,

If I deactivate WPML, activate Litespeed and reactivate WPML, it works, but it is impossible to activate the Litespeed cloud service when WPML is active.

Best regards,
Philippe

Hi Philippe,
Thank you very much for your feedback.

I created a sandbox site with a fresh WordPress + WPML + LiteSpeed installation, and the cloud service works with WPML plugins enabled. You can double-check it using this link: hidden link

This means the issue is on your site, not a compatibility issue between LiteSpeed and WPML.

Can you ask your hosting providers to check on the server side if there is any configuration, firewall rule, or security directive that might be causing this issue? Also, ask them if there is any error in the server logs. This might provide info about this behavior.

Looking forward to your message.
Best regards,
Carlos

Hi Carlos,

Thanks for this. Do you mind me sharing the link of the sandbox with a person I know within the hosting company ?

I am using two different hosting companies and experience the same, but they have more or less the same setup and security features.

Best regards,
Philippe

Hi Philippe,

Yes, sure, this is a sandbox site for testing purposes 🙂
