Hi,  
  
  
  
i’m using the last version of Mautic downloaded from this website.  
  
  
  
Server setup :  
  
  
  
Apache, Php 7, Cpanel  
  
  
  
When i click on email setting \> test connection (in mail send setting) nothing happened, in chrome console i could see an “error 500” then i checked the logs and found this :

Revert back to 2.5.1 for the time being. Until the developer come up with the stable release beyond version 2.6.
