Horizon errors ("The Mix manifest does not exist")

[joenepraat]

Since last commits, Horizon would not load in the webbrowser and gives errors (see below). I did composer install, all usual artisan commands and restarted horizon. Horizon is running normal in the background.

Error in the webbrowser:

`ErrorException thrown with message "The Mix manifest does not exist. (View: /var/www/pixelfed/vendor/laravel/horizon/resources/views/layout.blade.php)"

Try running:

php artisan horizon:assets \
&& php artisan horizon:install

@techknowlogick Thanks, that worked. Did I miss somewhere the memo?

Closing the issue.

@jeroenpraat I update pretty much daily (yay bleeding edge) and ran into the same problem you did, I found the above command posted to one of the pixelfed social accounts (can't remember which one right now).

Thanks @techknowlogick . Maybe @dansup can put this info in the commits somewhere (or I didn't look correctly).
