Im getting the following error in Chrome, and everything is “fine” in Safari.  
  
  
  
“XMLHttpRequest cannot load [http://mautic.mydomain.com/mautic/mtc](http://mautic.mydomain.com/mautic/mtc). Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘[http://mydomain.com](http://mydomain.com)’ is therefore not allowed access.”  
  
  
  
Any suggestions?
