Problem: The client is experiencing a 'Download failed. (Forbidden)' error when attempting to update or download WPML plugins, even after deregistering and registering the sitekey. Solution: 1. Revalidate your domain with your sitekey by navigating to https://wpml.org/account/sites/ and copying the sitekey created for your domain. Then, go to WP > Plugins > Add new > Commercial Tab > Deregister and register the sitekey again. 2. If the issue persists, manually install the plugin. Download WPML manually by visiting https://wpml.org/account/downloads/, scroll down, and click on 'Download WPML manually'. Then, in your WP dashboard, navigate to WP > Plugins > Add new and upload the downloaded zip file directly.
If these steps do not resolve your issue, or if the solution becomes outdated, we recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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. If you still encounter problems, please open a new support ticket at WPML support forum.
