Customer login not working

Hello guys,

I’m testing the plugin and all seems so cool. But i got a basic issue that i don’t know how to fix it or what i did wrong in the settings. I’m able to create new users (as customers) and it is all ok in the user section of WordPress. But then, when trying to login in the Client Portal, nothing happens. No error message, no nothing. It keeps in the login page. Can someone give a clue of what it might be? Thanks

The page I need help with: [log in to see the link]
