Issue (Redirect) on my brasilian language .com.br becomes .com.br.br

– permalinks settings : https://www.myname.com/exemple-article/
– Static front page for all lang
– Polylang settings : language determined by domain name

United States : https://www.myname.com
France : https://www.myfrenchname.com
English : https://www.myname.co.uk
Italiano : https://www.myname.it
Espa?ol : https://www.myname.es
Bresil : https://www.myname.com.br

Everything works correctly on all my languages, except the Brazilian version.

The homepage appears well as some pages with custom template (ex: custom type taxonomy, custom post type archive, etc…) but all the other pages are redirect like the exemple below :

https://www.myname.com.br/slug-page

https://www.myname.com.br.br/slug-page

I search in my htaccess file (nothing weird), in my database (no result on something like “.br.br”), desactivate some plugin.

PS : I have an error when I save my settings in polylang for all my domain (Polylang n’a pas pu accéder à l’adresse web https://www.mydomain.com/?deactivate-polylang=1. Veuillez vérifier que cette adresse web est valide.), If this is related…

PS2 : result of redirect check :

https://www.mydomain.com.br/caracteristicas-brasilian/
