Problem: The client moved their website from a local environment to the same live domain and WPML is asking whether the site is a copy or if the address has changed. Solution: We recommend selecting 'Yes/This is a copy - the original site is still working' if the local site is still operational. This will allow the client to use all previous translations. For more detailed instructions, please refer to our documentation on Using Advanced Translation Editor when you move or use a copy of your site.
If this solution does not apply to your situation because it might be outdated or not relevant to your case, we encourage you to open a new support ticket. We also 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 further assistance is needed, please contact us on the WPML support forum.
