Estou com problemas na execução do upgrade da versão 2.4.6 para a 3.0.2
O upgrade não finaliza e mostra os seguintes erros abaixo:
[code: Installer Installer::setFileUploader]
[code: Installer Installer::setFileName]
PHP Warning: get_class() expects parameter 1 to be object, null given in /public/lib/pkp/classes/submission/PKPSubmissionFileDAO.inc.php on line 358
PHP Fatal error: Uncaught Error: Call to a member function getFilePath() on null in/public/lib/pkp/classes/submission/PKPSubmissionFileDAO.inc.php:377
