Hi! After I update to 2.5.1, when I set API Settings to Enable:yes, now, I must fill the User/Authentication Settings (and I don’t have these data, so I fill with “test, test”). The other part can’t communicate with Mautic via API to see it’s segment list.  
  
  
  
Anyone can tell me what can I do to solve it?  
  
  
  
Thanks  
  
Igor
