Problem: You are trying to register WPML in a local development environment using Docker containers for nginx, PHP, MySQL, etc., but encounter an error stating that the site key doesn't match. Solution: If you're experiencing this issue, it's likely because the URL of your local environment differs from the one registered with the site key. We recommend obtaining a new site key for the new URL. You can follow the instructions here to re-register: How to re-register a site key for a new URL. Additionally, consider using the automatic WPML registration feature, which might be more suitable for your setup. Details can be found here: Automatic WPML Registration Using PHP.
If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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.
