Hi,
Trying to upgrade to the new stable version 11.4.1
I get the following error after replacing the /var/www/projeqtor folder by the new version downloaded:2024-10-25 08:57:18.136 ** ERROR ** [V11.3.2] ERROR **
2024-10-25 08:57:18.137 ** ERROR ** [V11.3.2] on file '/var/www/tool/saveObjectMultiple.php' at line (167)
2024-10-25 08:57:18.137 ** ERROR ***** [V11.3.2] cause = Undefined property: Activity::$ActivityPlanningElement_validatedEndDate

I have a message stating "upgrade in process" on the login screen and left it pending for more than half an hour, but to no avail.
Any idea on whats going wrong ?
