Hi,  
we just startet to use mautic and we have the following problem.  
If we are logged in the backend - clicking at “configuration”, the site  
does not appear.

In the logfile are these lines:

[2018-08-27 10:20:33] mautic.ERROR: PHP Error: Class ‘Mautic\ApiBundle\Form\Type\ConfigType’ not found - in file /home/netsh109308/html/app/cache/prod/appProdProjectContainer.php - at line 8588 [] []
