This thread is resolved. Here is a description of the problem and solution.
Problem:
You are setting up WPML to use a different domain (.no) for the Norwegian language on your site and encountering a 'not valid' error when adding the .no domain in WPML settings. The error persists regardless of the URL format used.
Solution:
First, ensure that the domains are configured correctly. Before setting the option in WPML, visit your new domains or subdomains. They should display the same site without redirection. We recommend checking with your hosting provider or domain registrar to resolve these issues.
If this solution does not apply to your case, or if it seems outdated, please check the related known issues at https://wpml.org/known-issues/, verify the version of the permanent fix, and confirm that you have installed the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. If issues persist, we encourage you to open a new support ticket for further assistance.
