This thread is resolved. Here is a description of the problem and solution.

Problem:
You are unable to update your plugins because the site key does not match when trying to register on your customer's homepage.
Solution:
This issue might be occurring because the site URL and the registered site URL differ, possibly due to variations like 'www' or without 'www'. Here are the steps we recommend:
1. Log in to your WPML.org account and navigate to the Sites page.
2. Delete the existing site key.
3. Log in to your site, go to Dashboard >> Plugins >> Add new plugin > Commercial tab and click the Unregister WPML from this site link if it exists.
4. Click the Register WPML link.
5. Click the Get a key for this site link to generate a new key.
6. Copy and paste the new key into the input box and press the Register button.
If the issue persists:
1. Go to WP Dashboard Menu >> Updates.
2. Click the "Check again" link.

If these steps do not resolve your issue, or if the solution seems outdated or irrelevant to your case, we highly recommend checking related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If needed, please open a new support ticket.

Hi there.

What might be happening is that the key is probably not set to the correct URL version here (http://wpml.org/account/sites).

Let me try to explain.

This issue usually happens when the site URL and registered site URL are different, e.g., with www or without www. Could you please delete the existing site key and create a new one by following the steps below:
 
1. Please login to your WPML.org account >> Go to the Sites page: https://wpml.org/account/sites/   
2. Delete the existing site key.
3. Please login to your site and go to the  Dashboard >> Plugins >> Add new plugin > Commercial tab and click the Unregister WPML from this site link if that link exists.
4. Then please click the Register WPML link.
5. Click the Get a key for this site link.
6. It will generate the Key for your site.
7. Copy the key, paste it back into the input box, and press the Register button.

If the notifications still persist, please try the procedure below: 
1. Go to WP Dashboard Menu >> Updates.
2. Press the "Check again" link and see if this resolves the issue. 

Please let me know how things go.

Kind regards,
Mihai Apetrei
