Good day,
I upgraded to OTRS 4.0.22 from an earlier 4.0.x version. Reason being so that we can use KIXCore 4.0.15 and KIX4OTRS 7.1.12 which are compatible with the aforementioned OTRS framework.
However after the upgrade of KIX, the main navigation menu has disappeared. What might be the cause? and how can it be resolved?
Regards,
