Hi guys,
I was running the upgrade process in a big OJS 2 portal and during our upgrade process from OJS 2.4.8-2 to 3.1.1-4 in the step
[code: Installer Installer::convertSupplementaryFiles]
we got this error:
PHP Fatal error: Call to a member function getStatus() on null in classes/install/Upgrade.inc.php on line 1354
any help would be useful, because the process is taking about 2h till it reach this stage.
