How do you configure MySQL to use InnoDB? Is there a risk for my other CMS?
Well, I checked support/public before checking the installation guide. Now I move all files and folders from public and yes, I think my patch are correct, ie. index.php:
require 'vendor/autoload.php';
$server = new Flarum\Http\Server(
Flarum\Foundation\Site::fromPaths([
'base' => __DIR__,
'public' => __DIR__,
'storage' => __DIR__.'/storage',
])
);
