When trying to update my Ojs from version 2.4.2.3 to Ojs 3.x then this log appears a blank screen with no functionality. Does anyone know why this?

Hi all,

Regarding:

Call to a member function getFileId() on null in /ojs_temp/rc-3.1.1/lib/pkp/classes/submission/PKPSubmissionFileDAO.inc.php on line 1029

According to Change galley PDF published OJS 3.1.x - #8 by marc, reviewing the file permissions and re-running the upgrade corrected the issue.
