Hello everyone,  
  
  
  
I downloaded the production version 2.4.0 and uploaded it to my webhost, but the installer doesn’t work. What did I overlook?  
  
  
  
My PHP version is 5.6.29  
  
[http://www.rive.be/assets/php/](http://www.rive.be/assets/php/)  
  
  
  
But the Mautic installer gives “500 Internal Server Error”  
  
[http://rive.be/assets/php/mautic/installer](http://rive.be/assets/php/mautic/installer)  
  
  
  
How to proceed? Don’t know what the cause of the error is, so I could fix it.  
  
  
  
Thank you for any advise one may have,
