The entire theme stopped working. In the error log it is output this error

Any idea what's causing this?

I ran into this problem because my controllers had
namespace App;
not
namespace App\Controllers;
For me, changing the namespace and making sure that the file names matched the class names (i.e. FrontPage.php for class FrontPage) solved this issue.

...Except in one case: The 404 template. I get the same reflection error, which I would fix in the same way...but it expects a class named 404, which PHP chokes on. I've tried shuffling the names around, but with no luck.

Ran into the same problem after updating "roots/sage-lib": "~9.0.0-beta.3" to "roots/sage-lib": "~9.0.0-beta.4" and "soberwp/controller": "dev-master" (from commit e9358ff to commit 93aa3cc).

Changing the namespace declaration did not fix the problem though.

@rolandp Check your composer.json file. It should be along the lines of:

"autoload": {
    "psr-4": {
      "App\\": "app/"
    }
  },
  "require": {
    "php": ">=7",
    "composer/installers": "~1.0",
    "illuminate/support": "~5.4",
    "roots/sage-lib": "~9.0.0-beta.4",
    "soberwp/controller": "~9.0.0-beta.4"
  },

@alwaysblank I kind of addressed how to get around this here #49 (comment) which should allow you to declare 404 templates.

[darrenjacoby]

There is a difference between dev-master and beta.4. dev-master uses PSR4, so @alwaysblank is correct. The class names need to be PSR4 complaint and the namespace needs to be namespace App\Controllers;

@alwaysblank interesting note on the 404, I'm doing a template override option (which will also address underscores in filenames) so that will be the best workaround. I believe PSR4 loading is worth that caveat.
