Problem: 1) The client receives an error indicating that WPML has detected a change in the site's URL after moving from a development subdomain to a new domain, despite updating the WPML license key. 2) Errors in Language settings prevent automatic translation because languages are not mapped to supported languages. Solution: 1) To resolve the URL change issue, navigate to WPML → Translation Dashboard and select the appropriate action on the migration banner. For more details, visit Using Advanced Translation Editor when you move or use a copy of your site. 2) After addressing the first issue, if language setting errors persist, go to WPML → Settings and ensure that a translation engine is selected.
If these solutions do not apply to your situation or seem outdated, we recommend opening a new support ticket. Additionally, please check related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the latest versions of themes and plugins.
