+#### Check the `config/bundles.php` file
+
+By default Symfony Flex will add FreshDoctrineEnumBundle to the `config/bundles.php` file. But in case when you ignored `contrib-recipe` during bundle installation it would not be added. In this case add the bundle manually.
+
+```php
+# config/bundles.php
+
+return [
+    // other bundles
+    Fresh\DoctrineEnumBundle\FreshDoctrineEnumBundle::class => ['all' => true],
+    // other bundles
+];
