Background of the issue:
I accessed to WordPress back-office for the site скрытая ссылка using the WPML plugin.
Recently, we migrated our website from a Web hosting solution to another, and so made DNS update.

Symptoms:
The WPML plugin is indicating that the current site has changed its domain name, but the value remains the same.
"Il semble que ce site était auparavant fonctionnel sur скрытая ссылка, mais qu’il l’est maintenant sur скрытая ссылка;

Same issue for скрытая ссылка and скрытая ссылка
"Looks like this site was previously at скрытая ссылка and now it’s at скрытая ссылка;

Questions:
Why is WPML indicating a domain name change when the value is the same?
And more importantly : how to solve this situation without side effect ?
