- Make sure you are checking the correct upload handler. The “\src\UploadHandler.php” is for the PHP web application. File manager uses its own upload handler in the richfilemanager-php package (i.e. \vendor\hkvstore\richfilemanager-php\src\Repository\Local\UploadHandler.php), if you don’t find it, you better delete the vendor folder and run composer update again.
