Thank you for reply. Now i was able to enter module settings. Have multiple alias, set language only at the ones with /en-us or /it

Do you think the issue about URL it's related to this? this issues is still present..

 

You should have a primary alias without a language and one for each of it.
if you cannot edit using UI, you may update it directly in the database, table PortalAlias. You need to restart DNN afterwards.
