This thread is resolved. Here is a description of the problem and solution.
Problem:
The client was unable to re-register WPML on their site, encountering errors like 'unable to parse data from service response' despite multiple attempts and reinstallations.
Solution:
We initially attempted troubleshooting without success and escalated the issue to our system team. After unblocking the site, we advised the client to:
1. Log in to their WPML.org account and navigate to the Sites page.
2. Delete the existing site key.
3. Log in to their site, go to the Dashboard >> Plugins >> Add new > Commercial tab and click the Unregister WPML from this site link.
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If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
