Upgrade to 2.2.1 Error

Product Support

I upgraded to 2.2.1 yesterday, and the database update failed. However, everything seems to work except for email sends receive this error:



Fatal error: Class ‘SymfonyComponentHttpKernelEventListenerValidateRequestListener’ not found in /home/rojecub8/public_html/mautic/vendor/symfony/event-dispatcher/ContainerAwareEventDispatcher.php on line 152



In my directory structure, the path SymfonyComponentHttpKernelEventListenerValidateRequestListener is actually SymfonyHttpKernelEventListenerValidateRequestListener. The component level is missing.



Guidance?
