Every time I need to update Mautic or install a new implementation I have CORS errors. My old Mautic was in version 1.2 so I decided to update it with a new configuration and environment. I tried using [Mautic.net](http://Mautic.net) but CORS NEVER WORKS. Now I’m using a Bitnami AMI, after importing all my leads (for the third time), I tried to link my forms to my website and there is the damn CORS error again.  
  
  
  
I’ve found a “solution”:

Even the tooltip info is telling that I can put the domains one per line, this doesn’t works.  
  
I can make it work ONLY filling this field with one single domain. I cannot add more domains because the CORS error strikes again.  
  
  
  
PS: Turning it OFF never worked for me.  
  
  
  
In time, even fixing the CORS problem I still not receiving my form’s data. I [started a thread in Support](https://www.mautic.org/community/index.php/8512-mautic-won-t-receive-data-via-ajax) for this.

What kind of problems have the Bitnami’s machine?
