Hi all,

I’ve got a couple of projects that’s built on Sage 9. So far I was able to use the solution in [this article](https://discourse.roots.io/t/is-there-a-way-to-use-sage-9-with-php-8-1/24435/2) but it recently stopped working and Wordpress returns a Fatal error.

**The error message:**

```
( ! ) Fatal error: Uncaught ReflectionException: Class "App\Controllers\App" does not exist in /www/kinsta/public/wordpress-test/wp-content/themes/sage_9.1/vendor/soberwp/controller/src/Loader.php on line *75*
( ! ) ReflectionException: Class "App\Controllers\App" does not exist in /www/kinsta/public/wordpress-test/wp-content/themes/sage_9.1/vendor/soberwp/controller/src/Loader.php on line *75*
```

**This is my composer.json file**

    }
  ],
  "require": {
    "php": "^8.1",
    "composer/installers": "^2.0",

  },
  "require-dev": {

  },
  "scripts": {

    ]
  },
  "config": {
    "allow-plugins": {
      "kylekatarnls/update-helper": true,
      "composer/installers": false
    }
  }
}
```

This only stopped working a couple of days ago. If I downgrade the PHP to 8.0 then there are no issues.

Thanks in advance.

Which **WordPress** - & **PHP** -version are you using when the error occurs?

See this thread: [Uncaught ReflectionException after composer update · Issue #55 · soberwp/controller · GitHub](https://github.com/soberwp/controller/issues/55)

Thanks @evance! It was exactly that, I found that a couple of hours ago.
