Upgrade to 2.10.0 gives Unable to generate a URL error

Updating to 2.10.0 results in the Contacts and Companies sections displaying the error:



The site is currently offline due to encountering an error. If the problem persists, please contact the system administrator.



In tyhe logs I get the error message:



[2017-09-08 08:57:58] mautic.ERROR: SymfonyComponentRoutingExceptionRouteNotFoundException: Unable to generate a URL for the named route “mautic_import_action” as such route does not exist. - in file /var/www/vhosts/katalysis.net/httpdocs/pages/app/cache/prod/appProdProjectContainerUrlGenerator.php - at line 513 [] []



How do I go about fixing this?

Ran /update/schema and all is well again now.
