Problem: You are trying to register a new license key for WPML because the URL of your site under development has changed, but you cannot find where to do this in the WPML installation. You are also looking for an alternative to the 'UNlink WPML' or 'UNregister wpml' plugin. Solution: If you're experiencing this issue, we recommend navigating to Plugins → All Plugins and then selecting the Commercial tab. From there, you can click on "Unregister WPML" (a link on the right), where you can add the new key.
Please note that this solution might be irrelevant if it's outdated or not applicable to your case.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. If this does not resolve your issue, please open a new support ticket at WPML support forum.
