This thread is resolved. Here is a description of the problem and solution.
Problem:
You are unable to update WPML due to a 'Site key not matching' error, which indicates that WPML cannot connect to its server for updates and security checks. This might be due to network or security settings blocking communication with wpml.org.
Solution:
If you're experiencing this issue, we recommend you try the following steps:
1) Visit https://wpml.org/account/websites/
2) If your site URL is already registered, delete it from the list.
3) Re-enter the site URL to generate a new site key.
4) Click on 'Show key' and copy the new site key.
5) Go to Plugins > Install > Commercial (Tab) on your WordPress site, and enter the new key to register WPML. If WPML is still registered, deregister it first.
This solution might be irrelevant if it's outdated or not applicable to your specific case.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.
