Form submit leads to "site is currently offline"

We’re having some issues with the submission of one of our forms (version 2.6 and 2.7 same issue). The form appears to post just fine to the Mautic Form dashboard but the end user gets a “The site is currently offline” message. This appears to work periodically but I cannot pin down what is causing this behaviour.



The error log writes teh following:

[2017-03-08 11:45:53] mautic.ERROR: SymfonyComponentDebugExceptionFatalThrowableError: Call to a member function getId() on null - in file /var/www/mautic/public_html/app/bundles/EmailBundle/Helper/PointEventHelper.php - at line 30



It’s important to note that the form is writing successfully but stops the users on our mautic installation.

This appears to happen only in Firefox (or at least Chrome is not affected)
